| 摘 要： | GPS因其优越的性能而得到广泛应用,但由于到达接收机的卫星信号相当微弱,所以很容易被外界电磁信号干扰。将智能天线技术应用到GPS系统中以达到抗干扰的目的。针对卫星信号的特点,提出了一种新的波束形成算法-Noise RLS算法。本算法用白噪声代替RLS算法中的参考信号,克服了RLS算法需要参考信号的缺点,仿真结果表明,提出的算法在不牺牲阵列自由度的同时又能获得更高的信干比。

| Abstract: | The Global Position System(GPS) is widely used for its great performance.But it utilizes low power spread-spectrum signals and thus is vulnerable to various types of strong interference sources.The smart antenna technology was used for suppressing jammers to GPS receivers.According to the features of GPS signal,a novel Noise RLS algorithm was proposed.The noise signal was introduced into RLS algorithm as reference signal to improve the algorithm.The simulation results show that,using N-RLS algorithm,higher signal-to-interference ratio can be obtained without reducing the degrees of freedom. |
