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.
