学通信的必看，几乎涵盖了同步的所有方面，包括符号定时和载波同步，老外总结的，很不错！-Learning to communicate Watchable, covering almost all aspects of synchronization, including symbol timing and carrier synchronization, foreigners summarize, very good!

In a series of papers in recent years new structures for coherent M-PSK (M-ary Phase Shift Keying) receivers were suggested. These include structures for carrier phase detectors for the carrier PLL (Phase Lock Loop), carrier PLL lock dete

A Novel Time and Frequency Synchronization Scheme for OFDM Systems A new training symbol is designed and a novel time and frequency synchronization scheme for orthogonal frequency division multiplexing systems is proposed. The time synchroniza
