摘要: A technique for estimating parameters adaptive antenna arrays in orthogonal frequency division multiplexing systems with co-channel interference is disclosed. Channel parameter estimation preferentially performed using a two pass process that advantageously expands the temporal scope (relative to single process) and considers past, present future channel estimations during estimation. are estimated by processing signals through fast Fourier transforms, filters, inverse transforms. The filters optimize based upon instantaneous correlation of received signals.
