Optical Code Division Multiplexing (OCDM) is a multiplexing scheme for optical communication that uses modified pseudo orthogonal M-sequence pairs as one of its spreading codes. These spreading codes generated by M-sequence, enable the effective removal of multi user interference. However, owing to limited number of M-sequences, few codes can be generated. To resolve this issue, we propose a method that applies the operation of modified pseudo orthogonal M-sequence pairs to gold sequences, and evaluates them.
