【摘要】 本算法利用接收信号自身作为本地相关信号,来探测接收相位,从而实现捕获过程。在初始阶段, 通过设计导频序列,以实现帧级的捕获和脉冲级跟踪;在传送信息过程中,收发端依据监测规则,保证传送信息过程中的同步。这样,通过一小段特定设计的导频信号,系统实现初始捕获和过程中捕获恢复。更多还原

【Abstract】 This paper utilizes the received signal itself which is a "dirty" template for containing thermal noise and multiple access interference as an auxiliary tool to complement synchronization in whole receiving process. In the initiation phase, a pilot symbol sequence designed is capitalized to assure frame-level acquisition and pulse-level tracking. During the conveying information, the transceiver synchronization is monitored. In this paper, several low complexity symbol sequences are supposed according to analyses. With a small number of pilot signal, the scheme show good performance by simulations.更多还原
