The design trade-offs of burst-by-burst adaptive Orthogonal Frequency Division Multiplex (OFDM) wideband speech transceivers are analysed. A constant throughput adaptive OFDM transceiver was designed and benchmarked against a time-variant rate scheme. The proposed joint adaptation of source- and channel-coder as well as modulation regime results in attractive, robust, high-quality audio systems.
