Hello All,
I want to generate a large length sequence which has a sharp auto-correlation.
I used a 15 bit PRBS sequence and got pn10.jpg. But I wanted a sharp correlation like only 0 and an impulse function like autocorrelation of golay sequences (golay.jpg)

But the problem is I have only unipolar input and no bipolar input, so I cant generate Golay sequence.
Moreover, I want no negative values in the auto-Correlation model since I want to precess it as log(auto-Corr), but golay seq are giving me negative values.
Can anyone please help me out with a solution.
Thanks
