Hao Li, Zhigang Wang, Houjun Wang · 2017
The paper presents an efficient high speed parallel blind equalization algorithm suitable for multi-mode signals in wireless communication system.The parallel algorithm combines the idea of coordinate transformation on the basis of the classical CMA.It converts a multi-mode signals into a constant-mode signal, so that the system error can be more toward zero.We also give a detailed implementation structure of the parallel blind equalization algorithm.The simulation results show that the proposed parallel blind equalization algorithm has excellent performance for modulated multi-mode signals, and the mean square error (MSE) value of the proposed algorithm is smaller than the classic CMA about 10dB.
