Because raw audio data is too large to transmit and stream in real-time, audio must be compressed (encoded) using a codec before it's streamed over Bluetooth A2DP (Advanced Audio Distribution Profile). Once the encoded audio is recevied by the output device, it is decoded before it can be played. The performance of a jointly optimised sub-band codec (SBC), channel codec, and post processing speech enhancement system for binary phase shift keying (BPSK) transmissions over Rayleigh fading channels is presented.
