| 摘 要： | 基于带通滤波器组的均匀数字信道化结构原型,根据软件无线电的模块化设计思想,提出了一种易于硬件实现的简单多功能数字信道化结构。能够实现2种抽取倍数:K=M和K=2M(K为信道数,M为抽取倍数)和2种滤波器组排列方式:偶型和奇型,两两组合形成的4种信道化结构。该结构针对不同信道化结构的要求,通过灵活配置模块,易于可编程门阵列(Field-Programmable Gate Arracy,FPGA)硬件实现。

| Abstract: | In this paper,an approach is presented to realizing a simple,multifunctional digital channelized structure which is easily implemented in hardware according to the concept of modularity of software radios.The proposed architecture based on the uniform digital channelized structure of band-pass filter bank provides four kinds of channel structures which are formed by different combinations of the decimation factor M and the arrangement of filter bank.In the proposed implementation of the filter bank,the numb... |
