Abstract
Satellite communication systems suffer from nonlinear intersymbol interference due to the limited bandwidth of the filters and the need to operate the onboard amplifier near saturation. We consider the blind equalization problem for this class of systems in a multichannel setting. By exploiting the bandpass nature of the channel and the statistical properties of PSK constellations, a simple necessary and sufficient condition for blind equalizability from the second-order statistics of the received signal is derived. An algorithm for the extraction of the equalizers is also given.
