A New Method of Baud Rate Estimation and Symbol Synchronization for Digital Modulated Signals
Yan Yao · Communications technology · 2009
In non-cooperative communications, baud rate estimation and symbol synchronization are important issues in realizing demodulation of digital modulated signals. To solve these problems, an analysis on current algorithms of baud rate estimation and symbol synchronization is given. Then a new method of baud rate estimation and symbol synchronization based on Haar wavelet transform (HWT) is proposed for digital modulated signals. By introducing multiple synchronizing reference points and synchronizing reference points correcting techniques, higher accuracy and anti-noise ability is obtained. The simulation results show that the proposed method outperforms the others.
