Research on the Method of Eb/N0 and SNR Conversion in Digital Communication System

基于实际数字通信系统中Eb/N0与SNR转换的需求,从Eb/N0和SNR的基本概念、定义出发,通过严密的公式推导,给出Eb/N0与SNR之间的一般性转换公式。并针对实际系统中白噪声的不同测量带宽,给出不同的Eb/N0与SNR转换公式。给出MATLAB系统仿真中Eb/N0与SNR的具体转换公式,最后通过实际通信系统的案例分析,给出实际系统的Eb/N0与SNR转换公式参数应用。

Based on the demand of Eb/N0 and SNR conversion in the actual digital communication system, presents the general conversion formula be-tween Eb/N0 and SNR through the basic concepts and definitions of Eb/N0 and SNR and the rigorous derivation. Presents the different Eb/ N0 and SNR conversion formulas for different measurement bandwidth of white noise in real system. Gives Eb/N0 and SNR conversion for-mula in MATLAB system simulation. Finally, through the case analysis of the actual communication system, gives the application of Eb/N0 and SNR conversion formula for the actual system.
