摘要 对相关衰落下,影响基于MIMO-OFDM技术的LTE系统容量的天线相关性、信道估计等参数进行了研究。基于矩阵的SVD分解,分析了收发端天线存在相关和信道估计误差情况下对系统容量的影响,并进行了相应的蒙特卡罗仿真。仿真结果表明,天线的相关性对系统容量的影响较大,随着信道估计误差的增加,系统容量有明显的下降。 Under multiple fading channels, factors that affect the capacity of LTE system based on MIMO-OFDM technology are researched. Based on SVD decomposition of matrix, average capacity with correlated antennas at transmitter and receiver are analyzed, and the effect of estimation error is discussed. The Monte-Carlo simulation presents that the effect of correlation among antennas are obvious, and system capacity is deceased deeply with the increase of channel estimation error.
