Keller, T., Münster, M. and Hanzo, L. (2000) A Turbo-Coded Burst-by-Burst Adaptive Wide-Band Speech Transceiver. IEEE Journal on Selected Areas in Communications, 18, (11), 2363-2372.
Turbo-coded burst-by-burst adaptive orthogonal frequency division multiplex (AOFDM) wide-band speech transceivers are proposed. A constant throughput adaptive OFDM transceiver was designed and benchmarked against a time-variant rate scheme. The proposed joint adaptation of source-codec, channel-codec, and modulation regime results in attractive, robust, high-quality audio systems, capable of conveying near-unimpaired wide-band audio signals over fading dispersive channels for signal-to-noise ratios (SNR) in excess of about 5 dB. Index Terms—Adaptive OFDM, audio compression, transmission, wide-band speech compression.
