摘　　要：论述了ＡＤＳＰ－２１００系列数字信号处理单片机的结构、性能等特点，并采用它实现了电力载波通道上音频高速ＭＯＤＥＭ的系统设计、算法选择和程序设计。讨论了采用通用高速数字信号处理单片机实现专用ＭＯＤＥＭ的优点和数字信号处理单片机在通信领域中的广阔应用前景，对推广数字信号处理单片机的应用具有重大的意义。Introduces both the architecture and the features of the ADSP-2100 family's DSP single-chip processor. Applying the DSP processor, a system of high-speed uppervoice band modem used on power carrier channel is designed, then the algorithm and the program for the system is chosen and fulfiled. Discusses the merits of implementation of special modem on general DSP processor, and its promising future of its use in communication fields. Hence the system will prove to be of significance for the promoting of application of DSP processors.
