Blind Equalization TXK Algorithm Based on QPSK System
Yu Shujuan · Journal of Nanjing Normal University · 2004
Because the channels for the actual digital communications signals are band limited and non ideal, symbol interferences will be caused, leading to high error rates if left uncompensated. The equalizers have been designed to compensate for the channel distortions. This article brings forward further the TXK Algorithm based on QPSK system. This algorithm can be applied to real SIMO channels. The principle is to estimate the transmission sequences by the evaluation of the real part of the channels. Simulation results indicate that this method of TXK has the better ability to equalize blind channels and to detect blind sequence in QPSK system.
