摘　　要：随着光纤信道传输速率的提升,偏振模色散(PMD)成为了限制光纤通信系统传输距离的主要因素,电域补偿技术是解决方案之一,但它又受到硬件实现复杂度及运算速度的限制。文章将并行处理技术及块最小均方(BLMS)算法应用到PMD补偿技术中,为电域补偿技术在高速通信系统中的应用提供了一条新的途径。With the increase of the transmission rate in optical fiber channel transmission,Polarization Mode Dispersion（PMD） has become the main factor in limiting the transmission range of fiber-optic communication systems and electronic dispersion compensation technology is one of the solutions,but it is restricted by the hardware complexity and computing speed.In this paper,parallel processing with Block LMS（BLMS） algorithms is used in PMD compensation,providing a new approach for the application of this technology in high-rate communication systems.
