Abstract

A range of Adaptive Orthogonal Frequency Division Multiplex (AOFDM) video systems are proposed for interactive communications over wireless channels. The proposed constant target bitrate sub-band adaptive OFDM (CTBR-AOFDM) modems can provide a lower BER, than a corresponding conventional OFDM modem. Furthermore, they can achieve an improved video quality performance across a wider range of channel SNRs, requiring typically 2-3dB lower channel Signal-to-Noise Ratios (SNR), than their fixed-mode counterparts.
