摘要
针对无线通信技术的特点和某型无线通信系统的功能需求,基于FPGA(现场可编程门阵列)软件无线电平台,使用VHDL(硬件描述语言)设计用于某型通信系统的数字信号处理关键模块。设计采用模块化的设计方法,在较小的硬件平台上实现系统的数字基带信号处理功能,这些功能包括语音与短信的发送、短信的编解码、系统工作状态的选择与切换,以及对外设接口的控制等。通过实验测试了模块的串口通信功能以及短信息和语音的组帧功能,测试结果表明,该模块各项功能指标符合要求,可靠性高且易于升级改造,相较于同类设计有了一定的改进和提高,具有较大的实用价值。
In view of the characteristics of wireless communication technology and the functional requirements of a certain type of wireless communication system,based on FPGA(field programmable gate array)software radio platform,VHDL(hardware description language)was used to design the key module of digital signal processing for a communication system.The modular design method was adopted,and the digital baseband signal processing function of the system was realized on the smaller hardware platform.These functions included the sending of voice and short message,the encoding and decoding of short message,the selection and switching of system working state,and the control of external interface.The serial communication function of the module and the framing functions of short message and voice were tested experimentally.The test results show that the functio-nal indexes of the module meet the requirements,have high reliability and are easy to be upgraded.Compared with similar designs,the module shows certain improvement and has great practical value.
