Finite-Step Algorithms for Constructing Optimal CDMA Signature Sequences

Joel Tropp, Inderjit Dhillon, Robert Heath Jr.

Abstract:   A description of optimal sequences for direct-spread code- division multiple access (S-CDMA) is a byproduct of recent characteri- zations of the sum capacity. This correspondence restates the sequence design problem as an inverse singular value problem and shows that the problem can be solved with finite-step algorithms from matrix theory. It proposes a new one-sided algorithm that is numerically stable and faster than previous methods.
