Method and apparatus for detecting a three-state signal in a base station in a wireless communications system

摘要

A decision as to whether a mobile terminal (202) has transmitted an ACK, a NACK or a NULL from a received signal at a base station (201) is made by successively eliminating (303, 304, 307) one of the three possible transmitted symbols by sequentially applying decision rules that maximize network throughput by minimizing the sum of the weighted costs of making a decision based on the magnitude of the received signal.
