基于DSP的软件无线电实验系统的设计

Design of SDR Experiment System Based on DSP

介绍了一种基于TMS320C6713的DSP芯片,拥有2.4GHz传输频率的软件无线电实验系统。该系统由核心数字信号处理器(DSP-Digital Signal Processor)、A/D,D/A转换器、收发信机三部分组成。由于该平台核心数据处理能力最高可达2400MI/s,收发频率高达2.4GHz,因此可以仿真大多数现有的编译码和调制解调算法。特别是其灵活的设计理念给实验者提供了一个开放的实验平台。最后,文章以通用数字调制设计为例,介绍了该系统的实际应用。

This paper introduces an experiment system of SDR, Soft Defined Radios, based on DSP chip TMS320C6713 with 2, 4GHz communication frequency. The system is made up of DSP （DSP- Digital Signal Processor）, ADC＆DAC with high speed and receiver ＆ transmitter. Most current algorithms of encoding ＆ decoding and modulation ＆ demodulation can be emulated by using this system because of its 2 400MI/S operational speed and 2, 4GHz communication frequency. Especially, its flexible design is based on provicling an open experimental platform. At last, the paper presents an application of this system with an example of the design of general digital modulation.
