摘要
本文提出了一种适用于窄带无线通信的数字信号频谱编码传输方法，就是用待传输的二进制数字信号对频谱进行编码，通过ＩＦＦＴ转换成普通的模拟信号发送出去．在接收端，对收到的模拟信号进行抽样、ＦＦＴ变换，恢复成原来的频谱，从而识别出发送端的数字信号．
This paper provides a spectrum-coding method suitable fot narrow-band radio communicationto transmit digital signal, which means to code the spectrum with the binary digital signal to be transmitted,thenconvert the spectrum to ordinary analog signal by IFFT and transmit it. At the receiving end,the received analogsignal is sampled and transformed to original coded spectrum by FFT, so that the digital signal of the transmissionend is distinguished.
