Then analyzes the performance of overcoming inter symbol interference (ISI) and inter channel interference (ICI) of the guard interval (GI) and the cyclic prefix (CP).

接着分析了保护间隔和循环前缀抗符号间干扰(ISI)和信道间干扰(ici)的性能。

We reduce the length of cyclic prefix (CP) while the number of carriers remains invariable and the optimal diversity combination coefficients were deduced.

在保持子载波数恒定的条件下减少循环前缀的长度，并推导出最优分集合并系数。

Under the basis of the existing cyclic prefix (CP) based timing synchronization method, we proposed a new blind timing synchronization method using adaptive beamforming.

基于循环前缀的同步算法实现简单，精度较高，但其仍然是一种半盲同步。
