摘要：

A high-spectral-efficient joint coding modulation diversity (JCMD) scheme over multiple-input multiple-output (MIMO) fading channels is proposed to meet the rapidly-increasing need of high-data-rate transmission in the future mobile communications. From a global viewpoint, the scheme introduces the space-time component interleaver and rotated modulation to jointly optimize the Turbo coding, QAM and MIMO processing. We firstly prove that the achievable rate of JCMD-MIMO is greater than that of the uniform-power-allocation BICM-MIMO. Based on the above theoretical analysis, an adaptive layer-selection JCMD-MIMO scheme with the optimum spatial component interleaver is proposed to obtain the maximum achievable rate. Simulation results turn out that this new scheme can obtain significant SNR gain as compared with the conventional BICM-MIMO schemes.
