Abstract

For free space optics to support multi user communications, multi-access schemes need to be incorporated. Conventional asynchronous optical code division multiple access (OCDMA) using optical orthogonal codes (OOCs) cannot deliver the required performance due to code interference, which sets a lower bound on the achievable bit error rate. Thus we introduce the use of complementary Walsh Hadamard codes as a promising solution to support synchronous OCDMA, capable of achieving required performance due to inherent interference cancellation, in addition to supporting a higher number of users while maintaining short code lengths, and alleviating some of the stringent requirements on the receiver hardware.
