A distributed wireless sensor network includes a plurality of sensors and a fusion center. The plurality of sensors sense the parameter to be detected from the source. The fusion center receives signals for the parameters from the sensors using multiple antennas, and determines the received signals to obtain information corresponding to the parameters. The received signal includes a binary hypothesis using parameters, a first channel between the source and the sensors, a second channel between the sensors and the fusion center, a first noise at the sensors, a second noise at the fusion center, Based on a binary hypothesis test. The fusion center determines the received signal based on a log-likelihood ratio (LLR) test.;
