ABSTRACT:
An iterative decoder for use in a WLAN includes an inner decoder/detector, a first subtraction module, a deinterleaving module, an outer decoder, a second subtraction module, an interleaving module, and a determining module. The inner decoder/detector determines inner coded bits and extrinsic information of the inner coded bits from symbol vector based on a channel matrix and inner extrinsic information feedback. The first subtraction module subtracts the inner extrinsic information feedback from the extrinsic information of the inner coded bits. The deinterleaving module deinterleaves the output of the first subtraction module to produce deinterleaved inner extrinsic information. The outer decoder determines outer coded bits and extrinsic information of the outer coded bits from the deinterleaved inner extrinsic information. The second subtraction module subtracts the deinterleaved inner extrinsic information from the extrinsic information of the outer coded bits. The interleaving module interleaves the output of the second subtraction module to produce the inner extrinsic information feedback. The determining module produces decoded bits based on the outer coded bits.
