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.
24123 此方案不需要调制方式等先验信息，复杂度低，灵活性好，适合非合作接收条件。 The scheme has a lower complexity, better flexibility while disregarding the modulation type, which made it a good choice for non-cooperative condition.
