A novel turbo-equalization algorithm for multicode CDMA with V-BLAST architecture
Xiaohu You · Journal of China Institute of Communications · 2005
To suppress the interference and improve capacity of multicode CDMA with V-BLAST architecture, a novel method of joint MMSE equalizer and Turbo decoding was proposed in this paper. Also, a novel Turbo equalizer structure was obtained. The receiver performs two successive soft input soft output, first from a MMSE equalizer and then from a Turbo decoder and was used as a priori information for the next iteration. Simulation results demonstrate that the proposed Turbo equalizer offers significant performance gain over traditional non-iterative receiver structures.
