摘要
基于数字信道化接收机的信号集合更新模型,提出了跨信道检测仲裁的集合更新算法及其实时实现结构.该方法以信号的频率特征为原则,与现有算法以信道特征为原则不同,解决了噪声环境中单载频信号和调频(FM)信号跨信道输出问题.理论分析和仿真结果证明了该算法的有效性.该算法已经应用于某数字信道化接收机.
A new cross channel detection and arbitration algorithm and its real-time implementation structure are proposed. The algorithm is based on a proposed signal collection update model of channelized receiver. The algorithm centers on the characteristics of signals instead of the characteristic of the channel itself, and thus can solve the cross channel problem of single carrier signal and frequency modulated（FM） signal in background noise. Simulation results indicated that it is an effective algorithm. The algorithm has been applied to a digital channelized receiver.
