The Study of Sky-wave Interference Cancellation Algorithm Based on APIC

摘要：

Marine radio-navigation system is based on spread spectrum system, whose working environment is complexity and usually works in a bad channel conditions. Strong sky-wave interference in the system affected the positioning accuracy seriously. Sky-wave is a typical fast time-varying signal with large range of amplitude and rapid changing. The general multi-user detection algorithm can not effectively overcome the interference, caused by sky-wave. In order to solve this problem, the paper presents a solution based on adaptive parallel interference cancellation (APIC) multi-user detection algorithm. The simulation result shows that the APIC multi-user detection algorithm can eliminate sky-wave interference effectively. It meets the system requirements and is suitable for engineering applications.
