各种数字调制的一种产生方法，很有意思的哦......(A variety of digital modulation method for forming a very interesting ...... oh)

自己写的信噪比计算工具snr2.m snr2(s2ana,fs,f0,fl,fh,bl,bh) s2ana: 待分析信号 fs:采样频率 f0:信号频率 [fl,fh]:信号能量分散带(Their signal to noise ratio calculation tool written in snr2.m snr2 (s2ana, fs, f0, fl, fh, bl, bh) s2ana: to be analyzed signal fs: sampling frequency f0: signal frequency [fl, fh]: the signal with energy dispersive)

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.)
