摘要：
The Global Positioning System (GPS) utilizes lowpower spread-spectrum signals which are vulnerable to many kinds of high-power interference signals and jammers. In this paper, we propose a low-complexity blind adaptive receiver that is based on a novel modified despreader and the one-stage constant modulus (CM) array. This system is capable of nulling directional interference and capturing the GPS signal of interest without requiring explicit angle-of-arrival (AOA) information. Computer simulations are provided to illustrate the performance of the multicomponent receiver for a combination of different types of jamming signals.
