STM-1中2 Mbit/s信号的解映射及去同步

The extraction of 2 Mbit/s signal from STM-1 and desynchronizing

论述了 STM- 1的解映射及去同步以获得 2 Mbit/s异步信号的实现方案 ,并提出了减小指针调整引起的抖动的自适应比特泄漏率算法 .FPGA、ASIC实现的硬件电路测试结果证明 ,文中论述的实现方法其性能完全满足 ITU标准 .

The realization project to extract 2 Mbit/s signal from STM-1 is discussed in this paper. The arithmetic of adaptive bit leak rate to reduce the pointer justification jitter is put forward. The FPGA, ASIC harder test results testify that the project introduced in this is paper is correct and the performances meet the ITU standard.
