Application of DSP on communication system

DSP is a kind of microprocessors, which has a special structure, so it is very fit for digital signal processing. It is one of the most popular and prospective techniques. Since the early of 1980′s the first DSP chip was invented, until now its capability has got a great development, and its application fields have continuously extended. At present, DSP has been a basic instrument in the communication field, computer, network, industry control, home facility and so on. Especially, digital signal processor has been applied in communication here and there, because of its ability of fast processing kinds of algorithm in digital signal processing on real time. In this paper, based on the character of DSP, the application on voice compressing and software radio technique and the chip selection of DSP during system design are introduced.
