本文阐述了作为数字信号处理基础的数字滤波器和各种变换技术中最引人注目的 Winograd 傅里叶变换及数论变换,并且,还概述了实时数字信号处理及其大规模集成电路,以及利用微处理机的信号处理。本文只涉及用于通信系统这一狭窄范围的最近发展动向,而没有涉及到用数字信号处理进行照片或模式处理等的非实时处理问题。最后,作为数字信号处理用于通信的例子,介绍了时分多路信号与频分多路信号相互转换的变换复接器。
In this paper, the most notable Winograd Fourier transform and number theory transformation among the digital filters and various transformation techniques that are the basis of digital signal processing are described. In addition, the real-time digital signal processing and its large scale integrated circuits are outlined, Microprocessor signal processing. This article deals only with the recent developments in the narrower range of communications systems and does not address non-real-time processing issues such as photo or mode processing with digital signal processing. Finally, as an example of digital signal processing for communication, a transform multiplexer is introduced in which the time division multiplex signal and the frequency division multiplex signal are mutually converted.
