摘　　要：为提高通信信号的抗干扰能力,保障信息传输的高速性与高可靠性。在卷积码编译码的相关理论及其算法的基础上,利用Matlab仿真软件包括M程序和Simulink对信息码源k进行仿真及结果比较。结果表明:卷积码编译算法能够有效提升信息抗干扰能力,卷积码的码率不变时,随着信道的噪声降低,误比特率降低,并体现良好的信息传输性能。In order to improve the anti-interference ability of the communication signal,and ensure the high speed and high reliability of information transmission,based on the relevant theories and algorithms of convolutional code coding and decoding,Matlab simulation software including M program and Simulink was used to perform the simulation and results comparing for the information source k.The results show that the convolutional code compiling algorithm can effectively improve the anti-interference ability of the information.When the code rate of the convolutional code is unchanged,as the noise of the channel decreases,the bit error rate decreases,and good information transmission performance is reflected.
