The Implementation and Performance Study of Bit Synchronization Method in High Speed Digital Receiver

摘要

Bit synchronization is one of the key technologies for the design and implementation of the high speed digital receiver, and is an important element to measure the reliability of its communication. The performance of synchronization will be influenced by many factors, among of which, symbol time delay and Gaussian white noise are the greatest. This paper systematically explains the realization principle of bit synchronization method based on interpolation. With the help of MATLAB tool, we have verified the feasibility of this method, obtained the impact of symbol delay and Gaussian white noise on the synchronization performance. In addition, we have gotten the stability results of the system in different SNR condition.
