32QAM adopts quadrature amplitude modulation, and the number of symbol series of each channel is equal. The answer is log(2

The answer is 5? Standard error! ! ! You can look at the constellation diagram of 32QAM, which is a 6×6 square. Except for four corners, there are exactly 32 points. Six points on one side need 3-bit binary numbers to represent, and orthogonal modulation needs 6-bit binary numbers to represent, so the answer should be 5, right?
