| 摘 要： | 提出了一个在非协作通信中对直接扩频序列(Direct Spread Spectrum Sequence,DSSS)信号的扩频序列进行估计的简单而有效的算法。在算法中我们提出了两个测度函数,一个用于搜索扩频序列在接收信号中的起始位置,另一个用于序列中的逐码片(chip)估计。理论分析和计算机仿真表明了此算法的有效性。

| Abstract: | The paper proposes an effective algorithm to estimate the spread spectrum sequence of Direct Spread Spectrum Sequence (DSSS) signal, which is suitable for non-cooperative communication systems. Two measurement functions are suggested. One is used for sequence synchronization; the other is used for sequence estimation chip by chip. Only simple complex addition and multiplication are required in this algorithm. Both theoretic analysis and computer simulations show the effectiveness of this algorithm. |
