| Abstract: |
| This paper presents an efficient Joint Coding and Modulation Diversity (JCMD) scheme. The proposed scheme applied modulation diversity technique to MIMO-OFDM system which can effectively use time, frequency and space diversity combined with channel coding. In fading channel, the proposed scheme not only achieves high spectral efficiency, but also greatly enhances the reliability of wireless transmission. The self-developed hardware prototype system proves that the proposed scheme can be realized and has high reliability. Compared with traditional MIMO-OFDM scheme based on bit-interleaved coded modulation (BICM), software and hardware simulation results show that the proposed scheme with the optimal rotational angle can obtain a significant performance advantage both for precoded and non-precoded system in the condition of non-perfect channel knowledge and non-ideal synchronization. |
