Abstract
A method for mitigating interference in a frequency hopping channel system based on codeword metrics obtained during decoding of codewords. The method includes decoding a plurality of codewords using a particular error control coding method. Each of the plurality of codewords includes portions received from plurality of channels in the frequency hopping channel system. For each decoded codeword, one or more codeword metrics are obtained based on the cost of correcting errors during decoding of the plurality of codewords. Based on the codeword metrics, one or more channel metrics are inferred. Based on the inferred one or more channel metrics, a reliability metric of a particular channel is reduced, or incoming symbols received from the particular channel are ignored during decoding.
