Blind Equalization Algorithm for SIMO Channel with Common Zeros
Hao Li · Jisuanji gongcheng · 2012
Based on a Single Input Multiple Output(SIMO) model with common zeros,a direct Infinite Impulse Response(IIR) blind equalization algorithm of SIMO channel with common zeros is proposed.The received signals are equalized by the IIR prediction equalizer,and the outputs are applied to an adaptive phase rotation algorithm.An optimal MMSE equalizer is introduced to gain better performance when receiver gauss white noise is present.The new algorithm can correct the phase error and reduce the sensitivity to the gauss white noise.Simulation experimental results show that IIR channel and channel with common zeros both can be equalized well by the algorithm.
