高阶调制(QAM,MQAM)信号中做基带映射,格雷码作为一种规范的映射规则,加上I,Q方向上相邻两个星座点对应的Bit_Cluster中只有一个Bit不同,所以有方便统一的特性。 以16QAM为例,先上Gray Code 16QAM星座图: 这样的映射有以下规则: 比特高2位,在I路符号从负到正方向,依次是00,01,11,10即2-bit格雷码 比特低2位...

Given a non-negative integernrepresenting the total number of bits in the code, print the sequence of gray code. A gray code sequence must begin with 0. Example 1: Input: 2 Output:[0,1,3,2]Explanation: 00 - 0 01 - 1 11 - 3 10 - 2 For a givenn, a gray code sequence may n...

LeetCode 89 Gray Code 题目 格雷码 000 001 011 010 110 111 101 就是相邻的两个码之间只变动一个bit, 格雷码的构造方法可以递推得到,它是一个有规律的序列。 具体n的格雷码,可以由n-1得到,方法就是如下图所示,摘自维基百科 当然也有通项公式,用位运算写起来,也巨简单,虽然不知道为什么:Gray[n] = n^...
