A simple and efficient method for using bipolar codes in noncoherent optical code-division multiple access systems is proposed. The proposed system requires only incoherent optical delay lines and direct detection receivers. Practical architectures for the encoder/ decoder are given. The Letter shows that combining Gold codes of period K = 4 into composite sequences of period N = 508 allows 20 simultaneous active users for Pe = 10-9, while requiring only four nonprogrammable delay lines.
