Abstract
This paper describes the matrix-theoretic ideas known as Welch-bound-equality sequences or unit-norm tight frames that are used to alternate minimizing the total squared correlation. This paper shows the construction of an optimal signature sequences for the synchronous code-division multiple-access (S-CDMA) channel in the presence of white noise and uniform received powers to solve inverse eigenvalue problems that maximize the sum capacity of the S-CDMA channel.
