摘　　要：介绍了以软件无线电技术为基础，构想一种高效的软件化全数字信道化发射机的基本原理和实现方法。基于多速率数字信号处理中的内插理论，结合多相滤波技术建立该发射机的数学模型，并进行多路信号发射的多相滤波器组的设计和计算机仿真，最后开展了以现场可编程门阵列(FPGA)芯片作为数字信号处理单元和基于高速PCI标准总线通信卡结构的信道化发射机的通用硬件平台的研制，结果表明该信道化发射机的设计方案是可行的。Based on the design of software radio technique, the implemental structure and basic principle for highly effective softened-all-digital channelized transmitter which is combined with interpolation theorem and polyphase filtering banks in multirate digital signal processing, is presented in this paper. And also its mathematic model is set up, then the results of multi-signal computer simulation and the universal platform composed of high speed standard PCI bus and FPGA chip as digital signal processing cell indicate that a technique to design all-digital channelized transmitter is feasible.
