高速链路系统的误码率（BER）算法实现

随着高速信令系统数据率的大幅攀升，以最坏眼图为指导势必导致系统的过量设计。针对这一现象，提出了以误码率（BER）眼图来指导设计的方法。通过给码型附加概率，卷积叠加运算得出一个BER眼图。该眼图不仅能显示眼图的各种可能情况，而且还能显示各个眼图发生的概率。仿真结果验证了该算法的有效性，能快速、高效、准确地求出系统各种情况的眼图及其发生概率。

Realization of the High Speed Link System BER Algorithm

Along with the high speed signaling system data rate rise sharply,regard worst case eye as guidelines will lead to excessive design.Aiming at this phenomenon,this paper puts forward a method of BER to guide the design.We add probability to the pattern,convolve the probability and then arrived at a BER eye.This eye can not only show all the eye but also show the probability of every eye diagram.Simulation results show the effectiveness of the algorithm which achieves fast,efficient and accurate calculation of the eye diagram and its probability of the system.
