说明：  Gold序列是基于m序列优选对产生的，是由两个长度相同、速率相同、但码字不同的m序列优选对模2加后得到的，一对长度为N的m序列优选对可以产生N＋2条Gold码。
(Gold sequence is based on the optimization of m sequences generated by both the length of the same, the same rate, but different m codeword sequence optimization of mode 2 increases obtained, a pair of length N of the m sequence optimization can generate N 2 Article Gold code.)
