程序给出了BOC信号的生成过程及其频谱、自相关函数图形。子程序包含GPS伪码、子载波的生成方法。对理解通过移位寄存器产生伪码的方法及BOC调制方式很有帮助。-The program gives the BOC signal generation process and its spectrum, the autocorrelation function graphics. Subroutine contains the GPS pseudo-code, sub-carrier generation. Helpful to the understanding of the shift register pseudo-code method.
