Turbo Space-Time Receiver by Kurtosis Maximization for CCI/ISI Reduction in Cellular Wireless Communications
Chun-Hsien Peng, Chia-Chin Lin, Tsung‐Hui Chang, Chong‐Yung Chi · 2006
Chi and Chen's computationally efficient fast kurtosis maximization algorithm (FKMA) for blind beamforming and equalization is applied to the design of the conventional cascade space-time receiver (CSTR) for blind co-channel interference and inter-symbol interference (ISI) reduction in cellular wireless communications using antenna arrays. However, the receiver performance is limited as the normalized kurtosis magnitude of the ISI-distorted signal of interest, denoted as /spl gamma/, is small. Then a blind turbo space-time receiver (TSTR) is further proposed that applies spatial and temporal processing using FKMA in a cyclic fashion to estimate the desired data sequence. The performance of the proposed blind TSTR is insensitive to the value of /spl gamma/, and therefore is superior to that of the blind CSTR. Finally, some simulation results are provided to support the efficacy of the proposed blind TSTR.
