摘要
本文分析了高分辨率参数估计算法-MUSIC在通过频率响应不一致(通道失配)情况下的统计性能,推导了通道失配对空间港的影响以及失配方差和分辨能力的关系表达式.理论表明:通道先配会引起空间谱误差并降低其分辨能力。计算机仿真结果证明了理论结果的有效性。
This paper analyzes the statistic performance of the high resolution parameter estimation algorithm (MUSIC) in the presence of channel mismatch. The relationship of theoretical expression between the spatial spectrum and channel mismatch, resolution ability and channel mismatch are derived . The theory shows, the effect of channel mismatch on the performance of the algorithm is seriously. These formulas were validated by comupter simulation.
