Comparison between adaptive algorithms using in GPS receiver

  • 摘要: 为了比较功率反演、多信号归类和最小范数自适应算法的抗干扰性能,研究了各算法的基本原理,并在均匀线阵中采用各算法进行仿真,比较各算法在有用信号和干扰来向上得到的天线增益.仿真中有用信号为-160 dBW的GPS卫星信号,两个同频干扰来自不同方向,并在仿真中改变干扰功率.仿真结果表明这三种算法都可以用于GPS接收机抗干扰.其中,功率反演算法抑制弱干扰的性能较差;多信号归类算法抑制弱干扰的性能较好,但会引入错误零陷;最小范数算法既可以抑制弱干扰,也不会引入错误零陷.
