本文提出两种时分多址信号格式下工作的四元阵自适应天线系统的实现方案。对宽带Gram-Schmidt正交化网络和宽带加权网络中的环噪声进行了分析。计算机模拟结果表明:此自适应天线系统在强干扰环境下能使信噪比提高40dB左右。
This paper presents two kinds of time division multiple access signal format quaternary array adaptive antenna system implementation. The ring noise in broadband Gram-Schmidt orthogonal networks and broadband weighted networks is analyzed. Computer simulation results show that this adaptive antenna system can improve signal to noise ratio by about 40 dB under strong interference environment.
