| Abstract: | Turbo coding and STBC-OFDM is cascaded to improve the performance and capacity of TD-SCDMA system. First introduces the scenario and the system model, then analyzes the capacity of TD-SCDMA system with STBC-OFDM, the last the STBC-OFDM system based on Turbo codes with two transmit antennas and two receive antennas was tested over the given coefficients. The results show that the use of Turbo and STBC-OFDM is greatly improved the performance and capacity of TD-SCDMA system. |
