The bit synchronization technology is widely used in digital communications,and the general method of bit synchronization is based on hardware.This paper presents a method of bit synchronization and data recovery that only based on software.The method uses the ratio relationship between the sub-carrier frequency and the bit rate.The method can be used in multiform PCM codes(NRZ-L,NRZ-M,NRZ-S,SPL,SPM,SPS) which are in medium or low bit rate.The method has been used in digital receiver,and gained good effects.
