Abstract
Systems, devices, and methods to improve signal detection of a receiver in communication systems, including receiving a signal having one or more distorted versions of a predetermined waveform as well as processing the received signal with a plurality of eigenfilters generated from eigenvectors of a covariance matrix of the predetermined waveform. Further a correlation output is generated by further processing the received signal with at least one matched filter formed from an eigenfiltered version of the predetermined waveform and identifying at least one peak in the correlator output. The peak may be used to improve performance of the receiver.
