Abstract
A method and system are provided for enhanced signal detection in a frequency selective fading channel. Improved signal detection is realized by replacing single matched filters with multiple matched filters. The single matched filter spectrum is partitioned by frequency into M matched filter groups, where M is a positive integer greater than one. The filter bandwidth of each of the M matched filters is less than the bandwidth of the single matched filter from which they are derived. The M matched filters are provided to filter in parallel fashion the input signal into M sub-spectrums of the signal. The input signal is filtered through the M matched filters and also sent to the energy detector. The matched filter outputs are combined and the received signal is detected using the combined output and the energy in the received signal.
