摘　　要：基于传统方法实现的多相结构信道化数字接收机资源占用过多,资源利用率不高,这一问题在信道数很多的时候显得尤为突出。文中提出了一种基于折叠技术的实现方案,通过对其中资源占用最多的部分进行适当的折叠处理,可以节约大量资源。系统各模块采用VHDL语言实现,通过Modelsim软件仿真证明了本方案可行,相比未采用折叠的方案而言资源的占用量明显减少,资源利用率提高了将近50%。The traditional method of realizing the polyphase-structures channelized receivers uses too many resources,resource utilization is not high,this problem is particularly prominent when there are many number of channels. An implementation based on folding is proposed, by folding the part which occupies the most resources,to save resources.Building systems using the VHDL language.The simulation results show the validity and feasibility of the design.Compared to traditional programs,this program significantly reduced the use of resources ,the resource utilization is increased nearly 50%.
