    Abstract

    A simple way to achieve standard bipolar capacity in optical code-division multiple-access (CDMA) systems by using only noncoherent delay lines and optical sources with short coherence time is proposed. The technique is based on Manchester encoding of each chip. It was shown that when a source with a repetition rate M times as fast as the bit rate is used, K delay lines are sufficient to produce a code length of M by K. This is accomplished by properly using E/O switches whose speed matches the repetition rate of the source. The use of Kronecker sequences to further simplify the optical encoders and decoders is proposed.
