IMPROVEMENT OF TRANSMISSION PROPERTIES OF MULTIMODE FIBERS USING SPREAD SPECTRUM TECHNIQUE AND A RAKE RECEIVER APPROACH

Abstract:
Multimode fibers are characterized by multipath propagation of optical signals and this leads to severe intersymbol interference at the output of the fiber. In this work an approach based on the Rake receiver is proposed to overcome this drawback. An optimization algorithm was developed and appropriate software was employed to apply the proposed methodology on specific multimode fiber. Extensive simulation results were produced and are presented herein. The numerical results have shown that the order of magnitude of the maximum data rate, R, supported at different CDMA gains, in order to achieve a Bit Error Rate value smaller or equal to a convergent point, is related to the length of the multimode fiber, L, by the expression R = dL−1 with d increasing from 106 to 107 (Kbps. m) when CDMA gain increases from 50 to 500.
