`DECLARATION OF JUNE ANN MUNFORD

`
`LGE 1028
`
`

`

`
`
`
`Attorney Docket No. 10,693,700
`IPR of U.S. Patent No. 19688-0196IP2
`
`1. My name is June Ann Munford. I am over the age of 18, have personal
`
`knowledge of the facts set forth herein, and am competent to testify to the
`
`same.
`
`2. I earned a Master of Library and Information Science (MLIS) from the
`
`University of Wisconsin-Milwaukee in 2009. I have over ten years of
`
`experience in the library/information science field. Beginning in 2004, I
`
`have served in various positions in the public library sector including
`
`Assistant Librarian, Youth Services Librarian and Library Director. I have
`
`attached my Curriculum Vitae as Appendix CV.
`
`3. During my career in the library profession, I have been responsible for
`
`materials acquisition for multiple libraries. In that position, I have cataloged,
`
`purchased and processed incoming library works. That includes purchasing
`
`materials directly from vendors, recording publishing data from the material
`
`in question, creating detailed material records for library catalogs and
`
`physically preparing that material for circulation. In addition to my
`
`experience in acquisitions, I was also responsible for analyzing large
`
`collections of library materials, tailoring library records for optimal catalog

`Attorney Docket No. 10,693,700
`IPR of U.S. Patent No. 19688-0196IP2
`
`search performance and creating lending agreements between libraries
`
`during my time as a Library Director.
`
`
`4. I am fully familiar with the catalog record creation process in the library
`
`sector. In preparing a material for public availability, a library catalog record
`
`describing that material would be created. These records are typically
`
`written in Machine Readable Catalog (herein referred to as “MARC”) code
`
`and contain information such as a physical description of the material,
`
`metadata from the material’s publisher, and date of library acquisition. In
`
`particular, the 008 field of the MARC record is reserved for denoting the
`
`date of creation of the library record itself. As this typically occurs during
`
`the process of preparing materials for public access, it is my experience that
`
`an item’s MARC record indicates the date of an item’s public availability.
`
`
`5. Typically, in creating a MARC record, a librarian would gather various bits
`
`of metadata such as book title, publisher and subject headings among others
`
`and assign each value to a relevant numerical field. For example, a book’s
`
`physical description is tracked in field 300 while title/attribution is tracked in
`
`field 245. The 008 field of the MARC record is reserved for denoting the
`
`creation of the library record itself. As this is the only date reflecting the
`
`inclusion of said materials within the library’s collection, it is my experience
`
`2
`
`
`
`
`
`
`
`
`3
`
`

`

`
`
`
`Attorney Docket No. 10,693,700
`IPR of U.S. Patent No. 19688-0196IP2
`
`that an item’s 008 field accurately indicates the date of an item’s public
`
`availability.
`
`
`6. I have reviewed Exhibit LGER1024, “Non-Uniform Constellations for
`
`ATSC 3.0” by Nabil Sven Loghin, et al. as published in IEEE Transactions
`
`on Broadcasting, March 2016.
`
`
`7. Attached hereto as Appendix LOGHIN01 is a true and correct copy of the
`
`MARC record for IEEE Transactions on Broadcasting as held by the Penn
`
`State University library. I secured this record myself from the library’s
`
`public catalog. The MARC record contained within Appendix LOGHIN01
`
`accurately describes the title, author, publisher, and ISSN number of IEEE
`
`Transactions on Broadcasting. The ‘362’ field of this record visible on page
`
`# indicates this collection includes the March 2016 edition of IEEE
`
`Transactions on Broadcasting containing “Non-Uniform Constellations for
`
`ATSC 3.0”.
`
`
`8. Attached hereto as Appendix LOGHIN02 is a true and correct copy of
`
`“Non-Uniform Constellations for ATSC 3.0” as published in IEEE
`
`Transactions on Broadcasting. I secured this PDF copy myself from the
`
`Penn State University library’s digital holdings. In comparing Exhibit
`

`
`
`
`
`
`
`

`
`

`

`
`
`
`Attorney Docket No. 10,693,700
`IPR of U.S. Patent No. 19688-0196IP2
`
`LGER1024 to Appendix LOGHIN02, it is my determination that Exhibit
`
`LGER1024 is a true and correct copy of “Non-Uniform Constellations for
`
`ATSC 3.0” by Nabil Sven Loghin, et al. as published in IEEE Transactions
`
`on Broadcasting March 2016.
`
`
`9. The 008 field of the MARC record in Appendix LOGHIN01 indicates the
`
`date of record creation. The 008 field of Appendix LOGHIN indicates the
`
`Penn State University library first acquired this journal as of June 22, 2000
`
`and still holds this journal in perpetuity. Considering this information, it is
`
`my determination that IEEE Transactions on Broadcasting March 2016 and
`
`therefore “Non-Uniform Constellations for ATSC 3.0” was made available
`
`to the public shortly after its initial release in March 2016.
`
`
`10. I have been retained on behalf of the Petitioner to provide assistance in the
`
`above-illustrated matter in establishing the authenticity and public
`
`availability of the documents discussed in this declaration. I am being
`
`compensated for my services in this matter at the rate of $100.00 per hour
`
`plus reasonable expenses. My statements are objective, and my
`
`compensation does not depend on the outcome of this matter.

`
`hereby declare that all statements made herein of my own knowledge are

`be true; and further that these statements were made the knowledge that

`Abstract—This paper introduces
`uniform constellation (NUC) in contrast to conventional uniform
`quadrature-amplitude modulation (QAM) constellations. Such
`constellations provide additional shaping gain, which allows
`reception at lower signal-to-noise ratios. ATSC3.0 will be the first
`major broadcasting standard, which completely uses NUCs due
`to their outstanding properties. We will consider different kinds
`of NUCs and describe their performance: 2-D NUCs provide
`more shaping gain at the cost of higher demapping complex-
`ity, while 1-D NUCs allow low-complexity demapping at slightly
`lower shaping gains. These NUCs are well suited for very large
`constellations sizes, such as 1k and 4k QAM.

`While conventional quadrature-amplitude modulation (QAM)
`employed signal points on a regular orthogonal grid, so-
`called non-uniform constellations
`(NUCs)
`loosened this
`restriction.
`Constellation shaping techniques have a long history:
`already in 1974, Foschini (now well known for his ground-
`breaking work on multi-antenna systems) and his colleagues
`proposed constellations, which minimize symbol error rates
`over an additive white Gaussian noise (AWGN) channel [4].
`Ten years later, Forney et al. provided a mathematical proof
`of the ultimate shaping gain limit [5]. This limit however
`only applies to the so-called signal set capacity. A more
`realistic capacity limit is given by the bit interleaved coded
`modulation (BICM) capacity [7]. In [8], several known con-
`stellations (e.g., square or rectangular grids) were compared
`with respect to this BICM capacity. Other methods to obtain
`shaping gain tried to heuristically force the constellation to
`look Gaussian-like [9], however lacking a mathematical proof.
`The optimization of constellations in the 1-dimensional space
`with respect to BICM capacity was first described in [10].
`In [11], constellations up to 32-QAM have been optimized in
`the 2-dimensional space to maximize BICM capacity for the
`AWGN channel and a range of SNR values. A summary of
`both optimized NUCs in both 1- and 2-dimensional space is
`given in [12], where constellations up to 1048576 points are
`examined.
`In general, signal shaping can be classified into two groups:
`probabilistic shaping, which tackles the symbol probabilities
`by using a shaping encoder, and geometrical shaping by mod-
`ifying the location of the constellation points. The former
`approach requires a shaping decoder at receiver side, which
`increases the overall complexity. The latter only requires to
