摘要/Abstract

摘要：

针对多天线信号合成中的相关噪声问题，给出了基于信噪比最大准则的最佳合成权值和合成信噪比，并利用噪声的互相关系数推导了合成增益，分析了相关噪声对合成造成的影响。数值结果表明合成增益只与各路信号间的信噪比之差以及噪声的互相关系数有关。

Abstract: The effect of the correlated noises on multi-antenna signals combining is considered.By exploiting the maximum SNR rule，the optimal combining weights and combining SNR are derived，the values of combining gain are given using the correlated coefficients of noises，and the impact caused by correlated noises is analyzed.Numerical value show that the combining gain only have connection with correlated coefficient and the differential SNR of signals.

Key words: multi-antenna, signal combining, correlated noises, combining weight
