Summary:A method for detecting a received signal by a Base Station (BS) in a communication system is provided. The method includes receiving a BandWidth Request (BW REQ) indicator, determining first interference signal streams representing BW REQ messages, determining whether the first interference signal streams include at least one second interference signal stream which is in a null state, determining a first Maximum Likelihood (ML) metric, determining a second ML metric for each of a case where a value of bits constituting each of third interference signal streams except for the at least one second interference signal stream among the first interference signal streams is 1, and calculating a minimum error distance of the BW REQ messages received from Mobile Stations (MSs) based on the first ML metrics and the second ML metrics.
