生成C/A码，C/A 码是用 m 序列优选对组合形成的 Gold 码。Gold码是由两个长度相同而互相关极大值为最小的 m 序列逐位模2 相加所得到的码序列。(C/A code is to use m sequence optimization of combination to form Gold code. Gold code is made up of two same length and cross-correlation bitwise modulus maximum value is the smallest m sequence 2 addition of code sequence.)
