| Abstract: | Conventional equalization algorithm in digital communication system generally require an initial training period during which a known data sequence is transmitted and synchronized at the receiver, so result in channel resource wasting and make the system more complex. For blind equalization algorithm, the inter symbol interference(ISI)can be eliminated without the initial training period. In this paper, a blind algorithm based on the cyclo stationary property of IF signal is advanced, which overcome the disadvantage of blind to phase information of CM algorithm, and it can converge efficiently in phase distortion and frequency error system. |
