Abstract :
We present two gigabit/s spectral-amplitude-coding O-CDMA techniques that use coherent multi-frequency light. The techniques achieve high beat-noise tolerance by either employing multi-frequency self-homodyne detection or using spectral M-ary ASK based on electrical-domain spatial-code spreading.
