`
`PHY options for increasing data rate
`• Increasing modulation order
`– RF more demanding
`• Increasing channel code rate (e.g. 3/4 to 7/8)
`– Viterbi decoder traceback length increases
`– Operating close to constellation capacity saturation
`• Increasing bandwidth
`– Spectrally inefficient (but: 255MHz become available)
`• Increasing number of transmit antennas
`– Costs: parallel RF chains; channel correlations
`• Purpose of study
`– Determine rate tables
`– Determine suitable combinations of PHY options

`
`Simulation Environment
`• 802.11a PHY simulation environment, plus
`– Higher order QAM constellations
`– Higher/lower channel code rates
`– TX/RX diversity/MIMO OFDM
`• ZF detection and soft post processing (shown in plots)
`• APP and reduced APP detection
`– Increased channel bandwidth, from 20MHz to
`40MHz (64 to 128 FFT)

`Simulation Assumptions
`• Perfect channel knowledge/synchronization
`•
`Idealized multipath MIMO channel
`– More optimistic than [3]
`– Sub-channels independent; exponential decay, Trms = 60ns
`– Quasi static (channel stays constant during one packet)
`• Packet length: 1000 bits
`• 10dB noise figure (conservative [4])
`• 5dB implementation margin (conservative [4])
`• Not yet incorporated in results:
`– Channel estimation
`– Packet detection, synchronization
`– foff estimation
`– Clipping DAC/finite precision ADC
`– Front-end filtering

`codes’ to increase range (Table 4-7)
`• MIMO: 2x3, 3x4 by 8dB better than 2x2, 3x3
`respectively (Table 9-12)
`• ZF detection is close to APP detection for 64QAM
`and higher (Table 6)
`• To achieve 100Mbps MAC throughput, a higher PHY
`peak rate than 2x54=108Mbps is required [16]; target
`of 150Mbps peak rate is a reasonable estimate;
`can be achieved by
`– more than 2 TX ant., as 2x54Mbps is just 108Mbps
`– or, 2 TX antennas, 128QAM and higher, code rate 7/8
`– or, 2 TX antennas and doubling bandwidth to 40MHz

`
`Some conclusions
`• At least 2 TX antennas required to achieve
`target peak rate of 150Mbps
`• 128QAM and higher, code rate 7/8 realistic
`candidates to achieve peak rate
`• 40MHz would allow to relax requirements on
`constellation size and code rate
`– 64QAM sufficient
`– Code rate 3/4 sufficient
`– Provides about 10m range increase for the same
`data rate
