摘　　要：本文从软件无线电的思想出发分析了实信号的数学表达式,结合正交变换算法理论,通过分析、比较几种常用的数字正交变换方法,并采用DSP开发板实现数字正交变换。并通过实现验证了软件无线电接收机采用DSP实现数字正交变换的可行性。this article analyzed the math expression of the real signal from the software radio. In the article, there were several numerals orthogonal transformations had been showed with orthogonal transformation theory. And the numerals orthogonal transformations had been realized with DSP. At last we realized that the numerals orthogonal transformations was right at receiver of the software radio, which was completed with DSP.

关 键 词：软件无线电 数字正交变换 DSP
