超宽带（UWB）系统的盲同步仿真程序，精度在一个帧，最后可以得出盲同步的MSE。不足之处请多多指教。附MSE-SNR图一张。-ultra-wideband (UWB) systems for the blind simulation program synchronization, the accuracy in a frame, Finally come Blind synchronization MSE. Deficiencies Department asked for more info

本协议适用于采用PL3100系列芯片的载波信道（即载波集中器与载波单元之间）间通讯；本协议内所有数据包的传输采用帧同步格式，标准数据通信速率为500bps。-This Agreement applies to the use of PL3100 series chip carrier channel [ie, carrier-concentrator modules and between the carrier] communication this Agreement, all packe

主要给出准循环的LDPC码编码实现方法，译码方法选择，并给出了帧同步的解决方法-Give the main quasi-cyclic LDPC codes achieve coding method, decoding method of selection, and give the frame synchronization solution

Synchronization is one of the most critical issues in ultra-wideband communications due to the short duration of the pulses. In this work, a semi-blind synchronization scheme based on maximum-likelihood techniques to recover both symbol and f
