Improvement of SNR with Chaotic Spreading Sequences for CDMA
Ken Umeno, Ken-ichi Kitayama
Abstract
We show that chaotic spreading sequences generated by ergodic mappings of Chebyshev orthogonal polynomials have better correlation properties for CDMA(code division multiple access) than the optimal binary sequences (Gold sequences) in the sense of ensemble average.
