摘要 对收、发端的天线相关为指数相关矩阵的多径衰落信道的MIMO-OFDM系统的信道容量进行了研究。分别对收端和发端的相关矩阵进行SVD分解,主要分析了相关矩阵中的相关系数和多径衰落的路径数量2个参数对对系统容量的影响,并进行了相应的蒙特卡罗仿真。最终的仿真结果表明:在大信噪比的情况下,随着相关系数的增加信道容量下降明显;在总功率受限时,容量随着路径的增加明显增加。 Capacity of MIMO-OFDM system with exponential correlation matrix and multi-path channel is studied.Based on SVD,the effect of correlation coefficient and multi-path number are analyzed.The Monte-Carlo simulation results indicate that the capacity of MIMO-OFDM system,in large SNR,would decrease obviously as the correlation coefficient increases,and it would increase with the increase of multi-path number at the limited total-power situation.
