Symbol Synchronization Based on Pulse Width Modulation
Qixing Chen · Communications technology · 2008
A symbol synchronization method for digital communication is proposed, and it is a indirectly inserted pilot frequency based on pulse width modulation (PWM). The power spectrum density (PSD) of the signal processed by PWM technology is deduced. The experiment results show that the PSD contains symbol synchronization signal, the digital symbol synchronization based on PWM technology is acceptable for digital communication system, and its principle and realization is rather pithy.
