摘要
数字信号处理(DSP)技术作为软件无线电的关键技术之一,在现代电子领域得到日益广泛的应用。首先简要描述了软件无线电的基本概念,在此基础上详细介绍了一种由TMS320C6X系列DSP实现,用于短波信号侦测处理的通用数字信号处理平台。分别讨论了该设备的硬件组成、工作原理和特点,并给出了基于DSP的调制样式识别、解调软件算法实现方案以及试验结果。
Digital signal processing（DSP）, which is one of the key techniques in software radio, has been widely used in modem electronic area. First, basic concept of software radio is described briefly. Based on this discussion, a type of general digital signal processing platform implemented by TMS320C6X series DSP is introduced in detail for reconnaissance and measurement of HF signals. The structure of hardware, working principle and characteristics of such equipment are discussed respectively. The implementation of DSP algorithm and experimental results are also presented for modulation recognition and demodulation.
