US 8,077,810 B2 · Apparatus for high data throughput reception in a WLAN

Abstract

An apparatus for high data throughput reception in a WLAN includes a receiving module, first and second determining modules, a generating module, and a producing module. The receiving module receives a symbol vector representing M streams of symbols transmitted via a wireless communication channel. The first determining module determines inner coded bits and extrinsic information of the inner coded bits based on the symbol vector, a channel matrix, and inner extrinsic information feedback. The second determining module determines outer coded bits and extrinsic information of the outer coded bits based on the extrinsic information of the inner coded bits, the inner coded bits, and a soft input soft output decoding process. The generating module generates the inner extrinsic information feedback based on the extrinsic information of the outer coded bits. The producing module produces decoded bits based on the outer coded bits.

A baseband processing module for a receiver comprising:

a first determining module for determining and outputting inner coded bits and extrinsic information of the inner coded bits based on a symbol vector, a channel matrix, and inner extrinsic information feedback, wherein M bit streams of data have been de-multiplexed into a single stream of data and the single stream of data de-interleaved to generate the symbol vector;
a second determining module for determining outer coded bits and extrinsic information of the outer coded bits by deinterleaving the inner coded bits output from the first determining module to produce deinterleaved inner coded bits and using the deinterleaved inner coded bits to represent the inner coded bits to determine the outer coded bits and the extrinsic information of the outer coded bits using a soft input soft output decoding process;
a generating module for generating the inner extrinsic information feedback based on the extrinsic information of the outer coded bits;
and
a producing module for producing decoded bits based on the outer coded bits.
