OFDM符号定时同步改进算法

A New Method of OFDM Timing Synchronization

提出在Schmidl&Cox算法的基础上,设计新的训练序列,并且加入循环前缀对同步性能的影响,将改进的Schmidl&Cox训练符号和循环前缀CP结合起来同时完成符号定时同步.并对改进的算法进行了仿真,结果表明,同步性能得到明显提高.

A new method is discussed based on Schmidl＆cox. A new training symbol has been designed and the affection of CP to the synchronization has been considered in the new method. Combining impwved Schmidl＆cox training symbol with CP is used to achieve the synchronization timing of symbols. The computer simulates the improved method and the simulation results suggest that the performance of synchronization is improved.
