Blind equalization for burst signals based on soft information of constellation

In this paper, we concentrate on equalization algorithms for amplitude and phase-modulated (APM) signals in non-cooperative burst communication, and have designed a multi-modulus blind equalization algorithm based on cyclic iteration. The algorithm could achieve a faster and more effective blind equalization while just using the samples of the receiver. Proposed scheme has a lower complexity, better flexibility while disregarding the modulation type, which made it a good choice for non-cooperative condition. Simulation indicates that the new algorithm has a superior on existing algorithms in converging speed, stable error, and durability.
