Abstract

A unique optical access technique is described in which the features of coherence multiplexing and code division multiple access (CDMA) are combined. For the realization of this technique, the transmitted data is precoded and modulated by PSK onto an optical carrier, to achieve self-homodyne detection. This technique is described and demonstrated experimentally. The detailed theoretical analysis of the system performance in coherent optical CDMA for asynchronous communication is carried out and compared with incoherent optical CDMA system which use intensity modulation and required unipolar codes.
