Abstract:
1. A method for high data throughput reception in a wireless local area network (WLAN), the method comprises: receiving a symbol vector representing M streams of symbols transmitted via a wireless communication channel; producing a first output of inner coded bits and a second output of extrinsic information of the inner coded bits based on the symbol vector, a channel matrix, and inner extrinsic information feedback; subtracting the inner extrinsic information feedback from the extrinsic information of the inner coded bits to produce current inner extrinsic information; deinterleaving the current inner extrinsic information to produce deinterleaved inner extrinsic information; deinterleaving the inner code bits to produce deinterleaved inner code bits; determining outer coded bits and extrinsic information of the outer coded bits based on the deinterleaved extrinsic information, the deinterleaved inner coded bits, and a soft input soft output decoding process; subtracting the deinterleaved inner extrinsic information from the extrinsic information of the outer coded bits to produce current outer extrinsic information; interleaving the current outer extrinsic information to produce the inner extrinsic information feedback; and producing decoded bits based on the outer coded bits.
