摘要
根据无碰撞区(No Hit Zone,NHZ)跳频码的特点,提出了一种基于NHZ跳频码的跳频通信系统多址接入准同步组网方案.仿真结果表明,该方案保证了跳频系统工作在NHZ跳频码的无碰撞区范围内,有效地降低了系统的多址干扰,改善了系统的整体误码率性能,适合于多用户跳频通信系统.
According to the characteristics of No-Hit-Zone (NHZ) hopping code, a multi-access quasi-synchronous scheme based on NHZ hopping code for frequency hopping communication system was proposed. Simulation results prove that the scheme assured the frequency hopping system to work within NHZ hopping code. It decreases the multi-access interference and improves the integral bit error rate performance of the system, and is suitable for multi-user frequency hopping system.
