Sub-Band Adaptive Pre-Equalised OFDM Transmission
Power-efficient pre-equalisation techniques for subband adaptive OFDM transmissions are proposed as an effective means of improving the overall system performance in fading time-dispersive channels. The effects of the time-variant channel are examined and it is shown that adaptive modulation techniques are well suited to pre-equalisation. A range of different throughput and different target bit error rate (BER) systems are designed, which exhibit different amplifier back-off requirements.

Abstract

Power-efficient pre-equalisation techniques for subband adaptive OFDM transmissions are proposed as an effective means of improving the overall system performance in fading time-dispersive channels. The effects of the time-variant channel are examined and it is shown that adaptive modulation techniques are well suited to pre-equalisation. A range of different throughput and different target bit error rate (BER) systems are designed, which exhibit different amplifier back-off requirements. For example, the 10%, 1% and 0.01% target BER candidate systems exhibit bits per symbol (BPS) throughputs of about 2, 3 and 3.8 around the channel SNR of 15 dB over the investigated 155 Mbps, 60 GHz propagation frequency wideband Wireless Asynchronous Transfer Mode (WATM) channel.
