Normalized autocorrelation property of the m-sequence and the Gold sequence. The generation of the m-sequence is based on a simple sequence register generator (SSRG) with an order of 6, and the Gold sequence is generated with two m-sequences with the order of 6 using the parallel generation structure.[ 23 , 24 ] For the m-sequence, the ratio of the correlation peak value to the second peak value, termed as the peak ratio, is 10.5, while for the Gold sequence it is only 3.7. It means that the m-sequence has a better autocorrelation property for detection than the Gold sequence under the same condition.
