一种突发通信信号检测与频偏估计算法
An Algorithm of Signal Detection and Frequency Offset Estimation in Burst-mode Transmission
摘要
Abstract
This paper presents a signal detection and frequency offset estimation algorithm by performing FFT transform to synchronization symbols in a preamble. Compared with common algorithms,it can perform signal detection and frequency offset estimation simultaneously,also it can operate under the condition of lower signal-to-noise,larger carrier frequency deviation and larger signal dynamic range.The method is readily implemented in burst-mode transmission. The paper analyzes and simulates the algorithm based on the known theory and simulation results show that thirty-two synchronization symbols in a preamble can achieve effectively signal detection and frequency offset estimation.关键词
