Cc. Hsiao et al., MULTIPLE-ACCESS IN THE PRESENCE OF OPTICAL-BEAT AND COCHANNNEL INTERFERENCE USING WALSH-CODE-BASED SYNCHRONIZED CDMA TECHNIQUE, IEEE photonics technology letters, 9(8), 1997, pp. 1173-1175
We experimentally demonstrated the feasibility of using Walsh-code-has
ed synchronized code-division-multiple access (S-CDMA) technique to ac
hieve multiple access in the presence of optical-beat interference (OB
I), This multiple access technique can, thus, be applied to WDMA netwo
rks using subcarrier-based common wavelength signaling, or PON's which
generally do not have wavelength control on uplink laser diodes.
