New bounds on the total squared correlation and optimum design of DS-CDMA binary signature sets.

New bounds on the total squared correlation and optimum design of DS-CDMA binary signature sets.

The Welch lower bound (see Welch, R.L., IEEE Trans. Inform. Theory, vol.IT-20, p.397-9, 1974) on the total squared correlation (TSC) of signature sets is known to be tight for real-valued signatures and loose for binary signatures whose number is not a multiple of four. We derive new bounds on the T...
