| 摘 要： | 本文重点研究了软件无线电(Software Defined Radio,SDR)中不同信道的处理技术,其技术关键在于构建不同频段的数字滤波器进行不同信道信息的接收处理.在建立软件无线电信道模型的基础上,利用MATLAB实现了多阶FIR滤波器的设计,并将算法移植到DSP软件设计当中,在DSP的集成开发环境CCS下对FIR滤波进行了仿真,仿真结果达到了SDR的信道处理要求.

| Abstract: | The paper mainly studies the processing technique of different channels in SDR(Software Defined Radio).The key technique is to design digital filters of different frequency bands to receive the information of different channels.Based on founding the model of SDR channel processing,use MATLAB to realize the design of FIR filters by setting different parameters and transfer the arithmetic to DSP software design.After that,use CCS to simulate the FIR filter.The effect can reach the demand of channel processing... |
