Design of Software Radio Channel Codec Waveform Module Based on Xilinx ZYNQ Series Processor

信道编解码波形组件是软件无线电设计的关键组件。在无线通信中,信道编解码能够极大降低通信过程中的突发错误。在软件无线电设计时,要求波形组件软件化、宽带数字化以及灵活可重构。介绍一种部署于Xilinx ZYNQ系列硬件平台的信道编解码波形组件设计方案,该方案设计的波形组件通过超长的码长支持实现宽带化,通过参数的配置实现灵活可重构。结合流水线操作可知,该设计具有低时延及低资源消耗的特点。

Channel codec module is the key component of software radio design.In wireless communication,channel codec can greatly reduce the burst error in the process of communication.In software radio design,waveform components are required to be software-based,broadband digital and flexible and reconfigurable.This paper introduces a design scheme of channel codec waveform components deployed on Xilinx ZYNQ series hardware platform.The waveform components designed in this scheme realize wideband through ultra-long code length support,and realize flexible reconfiguration through parameter configuration.Finally,combined with pipeline operation,this design has the characteristics of low time delay and low resource consumption.
