When the difference of code phase between the received and the local(BOC(1,1)) signal lies in the half code chip,the signal acquisition rate increases from 33.3% to 100%,and the code phase range increases from 1/6 to 1/2 chip width by simulation.

• 仿真结果表明；捕获码相位差在半个码片内时；BOC(1；1)信号的捕获率从33.；3%25提高到100%25；码相位捕获范围从1/6码片增大到1/2码片
