METHOD AND SYSTEM FOR PREDICTING CHANNEL QUALITY INDEX VALUES FOR MAXIMUM LIKELIHOOD DETECTION

摘要

Aspects of a method and system for predicting CQI values for ML detection in a KxK MIMO system are presented. In one aspect of the system, a CQI value for a KxK MIMO communication system may be computed by decomposing the KxK MIMO system into a series of 2x2 MIMO systems. For each 2x2 MIMO system a CQI value may be computed by by reverse mapping a PER computed for the 2x2 MIMO system and an SNR value for a SISO communication system. By summing CQI values among the series of 2x2 MIMO systems a CQI value for the KxK MIMO system may be computed. Based on the computed CQI value for the KxK MIMO system, a coding rate may be selected. The selected coding rate may be selected to maximize a computed information throughput rate at a MIMO receiver that utilizes ML detection.
