A METHOD AND APPARATUS FOR ITERATIVE RECEIVER STRUCTURES FOR OFDM/MIMO SYSTEM WITH BIT INTERLEAVED CODED MODULATION BASED ON SOFT OUTPUT M ALGORITHM WITH MMSE PRE-FILTERING
摘要
The techniques and components described herein may improve the performance for a class of reduced-complexity receiver designs for coded OFDM MIMO systems with bit interleaved coded modulation. The receiver structures described are soft-input soft-output inner/outer decoder receiver structures that include one or more of the following: 1) an inner decoder that includes a linear front-end followed by a limited tree-search based on a soft-output M-algorithm; 2) a conventional near-optimal or optimal decoder for the outer binary code; and 3) iterative decoding (ID), whereby decoding (output) information is passed from one decoder module as input to the other and used to refine and improve the inner/outer decoding module outputs.
