  • For the characteristics of amplitude and phase-modulated signals in non-cooperative burst communication like less known information, less data, and low signal to noise ratio, Modified Constant Modulus Algorithm (MCMA) is concentrated on and a blind equalization algorithm is designed based on soft constellation information. The proposed algorithm could achieve a quick blind equalization while just using the statistics of the samples of the receiver and adopting the ideology of cyclic iteration. The scheme has a lower complexity, better flexibility while disregarding the modulation type, which made it a good choice for non-cooperative condition. The simulation indicates that the new algorithm has a superior on existing algorithms in converging speed, equalization result, and durability while keeping the performance on defensing noise, frequency offset and phase offset, and can be applied into engineering practice.
