Arm Processor In The Digital Communications Research

In this dissertation, an Embedded Application System Based on ARM processor is designed. This system is programmed to Modulate, Demodulate, Reed-Solomen code and decode , Convolutional code, Viterbi decode . Through loading different application program , this system can realize the function of communication with many kinds of signals .This text combines the designs of systematic hardware and software at first, has made an introduction to the application of ARM processor, then on the basis of analyzing signal modulating, demodulation algorithms such as ASK, FSK, PSK ,etc, have explained modulating, demodulation implementation method of the software. To Reed-Solomen code and decode, the convolution code, viterbi decode part, this thesis has mainly explained the programming method and programming skill on the basis of analyzing basic principle . In the article also unifies the actual design, has analyzed each part of procedures performance, has appraised the system traffic capacity.This thesis design has provided one kind of simple solution for the digital communication system, has the important reference value to the ARM processor in digital communication applied research.
