摘要

本工作致力于研究决定最优信号误码率(BER)性能的优化参数(相关系数)对其频谱效率和能量效率的影响。针对不同的限制条件，给出了最佳包络形状、相应的能谱和误码率性能曲线。考虑了占用的频率带宽和能量损失。在误差概率为10−3的情况下，获得能量损失不大于0.5 dB的相关系数值。发现在接近香农极限时，相关系数的减小是无效的。

Influence of Correlation Coefficient on Spectral and Energy Efficiency of Optimal Signals

This work is dedicated to researching the influence of the optimization parameter (correlation coefficient) which determines bit-error rate (BER) performance of optimal signals on their spectral and energy efficiency. Optimal envelope shapes, corresponding energy spectra and BER performance curves are presented for different limitations. Occupied frequency bandwidth and energy losses are considered. Values of correlation coefficient providing energy losses no more than 0.5 dB for error probability 10−3are obtained. The value of correlation coefficient which decrease is not efficient in terms of approaching to the Shannon limit is found.
