Different detection schemes using enhanced double weight code for OCDMA systems

Abstract

This chapter investigates the performance of enhanced double weight (EDW) code for spectral-amplitude-coding optical code division multiple access (SAC-OCDMA) system using different detection techniques. EDW code possess ideal cross-correlation properties such as the maximum cross correlation of one that are important characteristics in the optical CDMA systems since these can eliminate multiple access interference and reduce noise. The EDW code has numerous advantages including the efficient and easy code construction, simple encoder/decoder design, existence for every natural number n, and weight, which can be any odd number greater than one. The experimental simulation results as well as the transmission performances are presented in this chapter. © 2013 Springer Science+Business Media Dordrecht.
