Abstract :
An algorithm for automatic gain control (AGC) is proposed for a frequency hopped multilevel FSK system. The control information is gained only from the hard detected (binary) time-frequency signal matrices. According to this information the AGC algorithm adjusts the detection threshold close to the optimum, which corresponds to the minimum symbol decoding error probability. In the analysis of the algorithm, a multi-user radio channel is assumed.
