  • According to the features of TD-SCDMA system, a new MIMO structure of TD-SCDMA system based on midamble sequences is proposed. Furthermore, by combining Turbo iterative equalization and MIMO technology, MMSE-IC detection and MMSE-IC-Turbo detection are put forward. The two algorithms are measured with generally accepted RAKE-BLAST detection proposed in 3GPP. Simulation results show that MMSE-IC-Turbo detection performs best, and MMSE-IC also has better performance than the traditional algorithm. The capacity of TD-SCDMA system is largely improved by using the MIMO technology.
