HIGH DATA RATE COMMUNICATION SYSTEM FOR WIRELESS APPLICATIONS

摘要

A decoder (122) for a communication system includes an iterative decoding module configured to receive soft-input information bits (104). The iterative decoding module (104) iterates on probability estimates of the soft-input information bits to generate hard- decision output information. The iterative decoding module includes a plurality of arithmetic modules (120) operating to generate and process both backward and forward metrics substantially simultaneously using modulo arithmetic operations.
