| 摘 要： | 在时分多址(TDMA)通信网络中,由于COSTAS环会出现"悬隔效应"导致其不太适应突发方式载波恢复的解调要求。因此,提出了一种开环结构的全数字无前导字的突发8PSK解调方案。与常规算法相比,该算法可以在较低信噪比、较大载波频偏下工作,适合用于突发通信。在已有的理论基础上对算法进行了讨论,并给出了计算机的仿真结果。

| Abstract: | In a TDMA network,the hang-up occurred in COSTAS-loop makes it no longer suitable the burst demodulation any more.So,we proposed an open-loop-based method for estimating signal carrier frequency offset.Compared with common method,the open-loop-based method can operate in lower SNR and bigger frequency offset.In this dissertation we discuss mainly about the open-loop estimator,and simulation results and conclusions are given at the end. |
