Fine carrier synchronization algorithm based on similar property of the guard interval 基于保护间隔(GI)相似特性的载波细同步算法
In this scheme, the guard interval of between time slots is composed of the cyclic prefixed pilot sequences. 利用带循环前缀的导频序列作为时隙间的保护间隔(GI),构造了一种新的双循环正交的时隙结构。
In this paper, guard interval and cyclic prefix insertion in the OFDM system impact on the whole system performance. 本文研究了OFDM系统保护间隔(GI)和插入循环前缀对整个系统性能的影响。
According to the physical layer parameter analysis, the influences of the transmission and process delay on slot synchronization and guard interval setting were studied, and the guard interval length setting formula was derived. 基于物理层的参数解析,分析了传播时延和信号收发处理时延对于时隙同步和保护带长度设置的影响,给出了设置保护带长度的推导公式。
