Thread: Orthogonal problem in wireless

Hi,

Is it possible to have orthogonal equation with only -1 and 1 values only where the dot product of A.B, B.C and A.C will be 0 by just using -1 and 1? (eg. A = -1 1 , B = 1 1) ? Thanks.!!!

Is it possible in this scenario?

Are you sure that your only possible values are -1 and 1 and not -1, 0, and 1?

The problem is impossible with only -1 and 1 but possible with -1, 0, and 1.

Hi all,

Thanks for all those replies. I managed to calculate it using Walsh matrix and yes its possible.
