| 摘 要： | 误码性能是光纤数字传输系统的重要性能指标,而通常光同步数字传输系统(SDH, Synchronous Digital Hierarchy)又以误块性能来衡量其误码性能.通过分析光同步数字传输系统在背景噪声(用泊松分布来描述)和脉冲干扰(用A型传染病分布来描述)影响下的系统误块性能,推导出了泊松分布和传染病分布下误块率的一般关系式.

| Abstract: | The error code performance is one of the most important transmission performances for optical fiber digital transmission system. And for synchronous digital hierarchy(SDH), the error block performance is usually used to describe error code performance. The error block performance under the inference of background noise which is usually described by Poisson distribution and impulse disturbing which is usually described by Neyman-A contagious distribution were discussed for SDH system. The general relationship of error block ratio on Poisson distribution and Neyman-A contagious distribution was derived. |
