一种基于训练序列的改进的OFDM同步算法
An improved training-sequence-based OFDM synchronization algorithm
摘要
Abstract
On the basis of the study of S&C and Park algorithms,this paper proposes an improved training-sequence-based OFDM synchronization algorithm,in which only one training sequence is used.By using this algorithm,the plateau in timing synchronization is eliminated by multiplying the training sequence by difference sequence in time domain and the integer-carrier frequency offset estimated by the self-correlation of the training sequence between the receiver and transmitter in frequency domain.It is much better than the S&C algorithm in timing synchronization and carrier frequency offset correction.关键词
