一、引言在具有数据压缩功能的遥测系统中,某一采样时刻的数据是否需要传输是随机的,这就有可能导致传输帧的不等长性,给接收端的同步造成了一定的困难。为了与原有的接收设备兼容,通常将经过压缩处理后的数据在形式上排列等长的传输帧,来解决帧同步问题。这种等长的压缩帧所包含的实际内容却千差万别,必须使用计算机进行分路、解压后,才能恢复 I. INTRODUCTION In the telemetry system with data compression function, whether the data to be transmitted at a certain sampling time needs to be transmitted randomly or not is likely to result in the unequal transmission frame, which causes certain difficulties for the synchronization at the receiving end. In order to be compatible with the original receiving equipment, the compressed data is usually arranged in the form of transmission frames of equal length to solve the frame synchronization problem. This isometric compressed frame contains the actual content is vastly different, you must use the computer to branch, unzip to recover
