摘要
本文较详细地介绍了ＳＤＨ中的ＢＩＰ误码校验方式，推导了泊松分布下，ＢＩＰ误块率与误码率的一般关系式，给出了ＳＤＨ中几种典型的误块率与误码率的关系曲线。
This paper introduces in some details the bit interleaved parity(BIP)codes adopted in SDH for error monitoring,and derives the general relationship equation between BIP error block ratio and bit error ratio(BER)in the presence of Poisson distribution errors.Some of the typical curves of BIP error block ratio versus BER in SDH are also presented.Computer simulation shows its validity.
