A Novel Joint Combing Time-spatial Diversity Blind Equalization Algorithm

摘要：

According to the defects of constant modulus algorithm based on orthogonal wavelet transform (WT-CMA) ,and the inter-symbol Interference (ISI) caused by multi-path fading , a novel blind equalization algorithm is presented. In this proposed algorithm, FFT technique and overlapping retention algorithm are introduced firstly to realize WT-CMA in frequency domain (FWTCMA), which obtains a better performance and little computational complexity contrast with WT-CMA. Secondly, a new time-spatial structure is proposed which exploit the advantages of time diversity and spatial diversity with different combining modes to overcome the multi-path fading and the problem caused by the single mode effectively. Then, the presented structure is applied to the FWTCMA to get a novel joint combining time-spatial diversity blind equalization algorithm (JCTSD-FWTCMA). The simulation results show that the proposed algorithm has low Mean Square Error (MSE) and computational complexity, fast convergence rate.
