摘要
GPS信号的位同步是接收机定位环节中的关键一环，鉴于传统位同步方法等待时间长的缺点，本文提出了基于点积和直方图算法的位同步方法，利用点积输出结果作为位同步点的判定依据可以有效缩短定位等待时间，利用直方图算法可以提高位同步点的判定概率。
The Bit-synchronization of GPS signal is a key step to implement receiver＇s function. With the traditional Bit-synchronization waiting for long time, a method of bit-synchronization based on the algorithm of dot-matrix and square-graph is presented. The dot-matrix output is used to reduce greatly the bit-synchronization time; and the square-graph algorithm is used to improve the judging probability of the bit-synchronization
