摘要
基于硬件的信道化接受机需要占用大量的硬件资源,基于多相结构的信道化接收机是一种基于数字信号处理的全概率接收机,在实现上节省了硬件资源,依据多相结构原理推导出了基于多相结构的信道化接收机模型,并对得到的结论进行了分析与仿真。仿真结果表明,各个信道上通过仿真得到的信号与理论上输出是一致的,具有传统信道化接收机的性能。
Hardware structure channel receiver uses lots of hardware resources.Polyphase structure channel receiver that DSP is used in get full probability receiving ability and economize raw materials.Channel receiver model is drawed about signals processed with the theory of polyphase structure,analysis and simulation of the conclusion processed.Result of simulation demonstrates that outputs of all channels are consistent with forecast of the theory,with the function of channel receiver of classics.
