- 帧同步检测源码,包括同步跟踪模块,fifo,分频模块,还有系统的测试平台-frame synchronization source detection, including synchronous tracking module, fifo, frequency module, and system test platform
SDH
- SDH开销的接收处理,要求: 1, A1和A2字节为帧头指示字节,A1为“11110110”,A2为“00101000”,连续3个A1字节后跟连续3个A2字节表示SDH一帧的开始。要求自行设计状态机,从连续传输的SDH字节流中找出帧头。 2, E2字节为勤务话通道开销,用于公务联络语音通道,其比特串行速率为64KHz(8*8K=64)。要求从SDH字节流中,提取E2字节,并按照64K速率分别串行输出E2码流及时钟,其中64K时钟要求基本均匀。(输出端口包括串行数据和64K串行时钟)
sdh
- SDH是现代光纤通信中广泛应用的数据传输格式,在SDH帧结构中,前9列为开销字节,它包含了很多重要的信息,本程序为SDH开销的接收处理,查找帧头,分频,勤务话字节E1异步fifo。可拆为三段源代码,不知道能不能抵三个程序-SDH is a modern optical fiber communication is widely used in data transmission format, in the SDH frame structure, as the former 9 overhea
