【摘要】 讨论了一种在TDS-OFDM系统中利用PN保护间隔进行系统同步的方法,用本地生成的PN序列和接收到的时域数据进行相关,找到相关峰位置,利用相关峰位置完成定时同步,同时采用二次相关完成载波频率同步。通过仿真证明本同步方案具有较好的同步性能。更多还原

【Abstract】 This paper discusses a method, which uses pseudonoise (PN) guard interval for system synchronization in the TDS-OFDM. This method can be used to find the correlation peak and complete timing synchronization with the position of the peak by the correlation between the locally generated PN sequences and the received data in time domain. At the same time, quadratic correlation can be used in this method to complete carrier frequency synchronization. Simulation results show that this method provides better synchronization performance.更多还原
