摘要
突发通信系统因通信时间短而给突发信号的到达检测、载波相位及定时同步带来了困难。为此提出了一种基于能量归一和双峰值检测的突发信号检测方案,并基于两个相关峰信息完成了定时、载波、相位误差估计与补偿。仿真及实践结果表明,基于本文提出的突发信号检测及同步方案实现简单、性能优异。
Burst mode communication systems transmit signals in a short time, which makes it difficult to detect the signal arriving, carrier offset recovery, and timing. An algorithm of signal detection based on power normalization and double correlation peak-value detection is proposed in this paper, which can perform signal detection, timing, frequency, and phase synchronization at the same time. Simulation and practical implementation results show that the burst mode transmission signal detection and synchronization algorithm proposed in this paper is of less complexity as well as
