Spectral-amplitude encoding CDMA system based on high-speed electronic encoder/ decoder structures

Keywords: Optical fiber CDMA, spectral encoding, multi-Gbps networks, transversal filter, distributed amplifier, user orthogonality

Abstract

A new method for high-speed Code Division Multiple Access (CDMA) systems that lies on the analogue performance of distributed-based transversal filters is proposed. The method allows spectral-amplitude encoding CDMA system implementations leading to an improvement of orthogonality among users over temporal encoding direct-sequence systems. The maximal degrees of flexibility in the design of transversal filters are considered to generate waveforms that exhibit large temporal variation over the filter span time in accordance with an encoded waveform. Applications of our method to high-speed CDMA are discussed towards the end of the paper.
