Simulate, by using c++ ,a communication system consists of binary source, RS(7,3,5)/RS(128,122,7) encoder, BPSK modulator, AWGN channel, coherent demodulator, RS(7,3,5)/RS(128,122,7) BM decoder and sink。-Simulate, by using c, a communication system consists of binary source, RS (7,3,5)/RS (128,122,7) encoder, BPSK modulator, AWGN channel, coherent demodulator, RS (7,3,5 )/RS (128,122,7) BM decoder and sink.

MATLAB程序的仿真比较。随后，针对QPsK，详细讨论了其基本原理和具体的实现算法，并进行了仿真验证，然后选用HSP502巧数字上变频芯片和HSP50214B数字下变频芯片，设计了数字调制、解调器的实现方案。最后，作为对整个数字视频图像传输系统的宏观认识，利用M户JLAB中的实时建模仿真Simullnk库对典型的视频图像传输系统一数字视频广播系统(D vB)，进行了建模、仿真和初步的分析，结果表明:在高斯白噪声的传输环境下，系统采取的一系列抗干扰措施，包括内、外码级联的信道纠错编码和先进的调制技术(o FDM)等，保证了信源信息传输的有效进行。-MATLAB simulation comparison. Then, against QPsK to discuss in detail the basic principles and specific algorithm, a simulation test, and then choose the cleverest HSP502 figures HSP50214B frequency chips and digital down conversion chips, the design of digital modulation, demodulation for the realization of the program.MJLABSimullnk(D vB):Andean white noise transmission environment, the system adopted a series of anti-jamming measures, including internal and external codes Cascade Channel advanced error correction coding and modulation techniques (o FDM), ensuring a source of information for the effective transmission.
