A Design and Performance Analysis of a Loop-Locked Binary Code System with Automatic Phase Correction

在分析二相码编解码规则及二相码与位定时脉冲相位的基础上，提出了一个由位定时提取、二相码解码和帧同步检测构成的自动纠相的闭环二相码基带传输系统，理论和实验均表明本方法简单可靠。对闭环系统的性能进行了详细的分析，对一般的二相码基带传输系统具有一定的参考价值。

Based on the rules for binary phase coding,a loop-locked transmission system for abaseband binary code with automatic phase correction is proposed.Using the correctionphase pulse produced by synchronization system,this system can selected the correct phaseof binary code to realized the function of automatic correction phase,Experiments show thatthe system described is simple but reliable. The performance of the system is analyzed in detail. The logic design of the system is presented also.
