数字通信系统中采用基带传输和频带传输[ 1, 2 ] ,在抽样判决器之前,信号叠加了信道噪声. 本文利用

Matlab软件仿真[ 3, 4 ]分析了在判决器前叠加了高斯噪声后,信噪比与系统的误码率之间的关系.-Digital communication system using baseband transmission and band transmission [1, 2], in a sample before the decision device, the signal superimposed on the channel noise. In this paper, Matlab software simulation [3, 4] of the device in the sentence before the superposition of the Gaussian noise After the SNR and BER relationship.
