A spatial/frequency encoder-decoder scheme is proposed for optical code-division multiple-access (OCDMA) communications. The coders adopt codewords with multiple-weight-perrow property and can be realized via compact hardware. With the proposed decoding scheme, an intended user will reject any interfering user and theoretically achieve quasiorthogonality between OCDMA users. The performance degradation due to various noise sources in previous discussed one-dimensional coding scheme can be improved.
