摘　　要：针对软件无线电技术在舰船通信中应用问题,对软件无线电数字接收理论进行了深入研究,包括了低通采样理论、带通采样理论以及多速率信号处理技术等,同时对软件无线电结构进行了分析。采用软件无线电数字信道化模型,给出了信道化高效实现结构,并通过计算机仿真验证了该软件无线电数字信道化结构的正确性。该软件无线电信道化模型适用于舰船通信系统中应用。The software defined radio digital receiving principle, which including low-pass sampling principle, bandpass sampling principle and multi-rate signal processing technology, is studied in detail and the structure of software defined radio is analyzed according to the problem of software defined radio technology applied in ship communication. A kind of less aliasing and non-blind region channelized structure is given through deriving software defined radio digital channelized model. The structure of software defined radio digital channelized is proved connect by computer simulation. The channelized module based on software defined radio is suitable for the application of ship communication.
