摘要
基于对3G通信网络中阵列天线通道不一致性校正算法的性能分析,提出了一种基于参考信号源的自适应阵列天线通道不一致性校正算法。该算法充分利用了B.Friedlander算法和注入参考信号的校正方法的优点,通过使用参考信号的到达角估计值信息,来自适应地校正阵列天线中各阵元参数的不一致性,这些参数包括增益、幅度和相位因子。计算机仿真实验表明,推荐的算法大大改善了MUSIC算法估计来波信号方向的准确性,其性能远远超过了已有的各种校正算法。
Based on performance analyzes of the array antenna channel inconsistent calibration algorithms for 3G networks,an adaptive channel inconsistent calibration algorithm is proposed.The algorithm takes advantage of the B.Friedlander method and reference signal resource method to calibrate the inconsistent parameters of the elements,including gain,amplitude and phase factots.Simulation results show that the proposed algorithm improves the performance of the MUSIC algorithm and outperform the other ones.
