1995 Combinatorial BER analysis of synchronous optical CDMA with prime sequences
abstract
A previous BER analysis (see ibid., vol.39, no.11, p.1625, 1991) is based on a Gaussian approximation. We derive a combinatorial BER analysis and an improved Gaussian approximation for synchronous optical code-division multiple-access (S/CDMA) with prime codes. This analysis is shown to be in good agreement with the Gaussian approximation as well as with simulation results.
