现实生活的数字通信系统,情况复杂。存在着各种不同的调制解调技术,各种不同的编/译码方式。本文对不同的调制/解调方式下,不同传输条件下的数字通信系统进行仿真,最后通过对仿真结果进行比较分析,从而证明GMSK调制技术相对其他调制技术的性能优势。此外,在仿真过程中,还要通过设计一个传输计算机文件的仿真程序,说明传输计算机文件的可行性。
Real-life digital communication system, the situation is complicated. There are a variety of different modulation and demodulation techniques, a variety of different encoding / decoding methods. In this paper, we simulate the digital communication systems under different transmission conditions under different modulation / demodulation methods. Finally, the simulation results are compared and analyzed to prove the performance advantages of GMSK modulation technology over other modulation techniques. In addition, in the simulation process, but also through the design of a transmission of computer files simulation program, the feasibility of transmission of computer files.
