| Dec 14, 2013 at 14:11 | comment | added | Dilip Sarwate | This is far too detailed a question for this forum. You can try reading this answer and maybe you can figure out many of the answers for yourself. I will say that your demodulator is far too complicated. The same results can be achieved by simply using $(1+\operatorname{sgn}(x2))/2$ and $(1+\operatorname{sgn}(x2))/2$ as the decoded bits. | |
