dc.description.abstractThis paper investigates the application of subcarrier multiplexed code-division multiple-access (CDMA) techniques to image transmission over fiber-optic local-area networks (LAN's), In the hybrid scheme, CDMA is used to suppress the interference caused by the laser nonlinearity in the subcarrier multiplexing (SCM) fiber-optic communication systems, Likewise, the SCM scheme is able to increase the channel data rate of CDMA systems, This hybrid system combines the advantages of both schemes and is particularly well suited to subband coding that divides the image information into multiple parallel data streams using an analysis filter bank, each of which is transmitted via a unique subcarrier-code pair, where the spreading code and subcarrier frequency correspond to the image and one of its subbands, respectively, This hybrid scheme also allows more than one image to be transmitted and be accessed simultaneously at the same channel bandwidth, in which each image is assigned a particular spreading code added to its digital data modulating the subcarrier. After transmission, each received signal is independently recovered at a high-Q surface acoustic wave (SAW) receiver with the matching subcarrier-code pair, Other concurrent signals are rejected by the SAW, Then, all the recovered subbands are reassembled by a synthesis filter bank into a close reproduction to the original image, In this paper, the image quality of subband image transmission via CDMA/SCM fiber-optic channels is evaluated and examined.en_US
