Title:
ＰＳＫ信号の適応ブラインド等化方法、イコライザ、および受信器
Document Type and Number:
Japanese Patent JP5598390
Kind Code:
B2
Abstract:
The present application discloses a method for adaptive blind equalization of a PSK signal, an equalizer and a receiver. According to embodiments as provided, a conjugate product of a current output and a precedent output of an FIR filter is calculated, an equalization coefficient is updated using the conjugate product, and then an input signal is filtered using the FIR filter with the updated equalization coefficient. The embodiments as provided is applicable to adaptive blind equalization of any phase shift keying signal including a BPSK signal.
