N. Karafolas et D. Uttamchandani, SELF-HOMODYNE CODE-DIVISION MULTIPLE-ACCESS TECHNIQUE FOR FIBER OPTICLOCAL-AREA NETWORKS, IEEE photonics technology letters, 6(7), 1994, pp. 880-883
A new coherent technique for optical coding and decoding based on spre
ad spectrum principles is described. PSK modulation format is employed
along with delayed self-homodyne detection. This technique is describ
ed theoretically and demonstrated experimentally. An optical fiber Cod
e Division Multiple Access system employing the above spread spectrum
technique is proposed.
