In this paper, a specific proposal of hardware platform based on SCA software radio is introduced. A general communication platform with high flexibility and openness is built by DSP and FPGA devices after the estimation of resource requirements. The platform can implement the baseband signal processing and IF processing to achieve the multi - mode, multi - band, multi - channel and other communication functions.%介绍了一种基于SCA软件无线电硬件平台的具体设计方案,通过对平台的资源需求估计,确定以DSP+ FPGA为核心器件构建一套具有高度灵活性和开放性的通用通信平台,该平台能够完成信号的基带和中频处理,从而实现多模式、多频段、多信道等通信功能.
