| Abstract: | The combined usage of the iterative decoding of space-time block codes,OFDM system and LDPC code is discussed.The error-bit rate characteristics under Jakes channel model are also simulated by taking a turbo receiver for example.The results show that this method can effectively improve the system capability. |
