一种高效的短波多路信号并行接收算法设计与分析

均匀信道化和基于数字下变频（DDC）的信道化均为实现信道化滤波的基本方法。在基于短波宽带接收机的短波多路信号并行接收系统中，由于存在接收盲区、计算量大、结构不灵活等问题而难以直接使用。设计了频移交错双路均匀信道化和基于DDC的信道化相结合的算法，应用于短波多路信号并行接收中，具有无盲区信道化、高效处理等优势。文章详细分析了算法性能，讨论了子信道带宽、接收频点数与计算量的关系。

Design and Analysis of an Efficient HF Multiplexing Parallel Receiving Algorithm

Uniform channelization and channelization based on DDC are the basic methods for implementing channelization. But they are not applied in the HF multiplexing parallel receiving system based on HF broad band receiver due to blind zone, high calculation quantity and unvariable structure. This paper designs an algorithm which combines the frequency cross double uniform channelization and the channelization based on DDC. It has advantages of non blind zone, high efficiency in the field of HF multiplexing parallel receiving. The algorithm performance is analyzed in paricular, as well as the relationship of the subchannel band width, the receiving signal quantity and the calculation quantity.
