Conformation techniques for direct-sequence spread-spectrum wireless optical systems

Abstract

In this Letter the effect of using pulse conformation techniques over a DSSS wireless optical system is explored. The performances of both Gaussian and sinusoidal conformation over the spread and code signal are compared. As a pattern of comparison, the side‐lobe elimination for adjacent‐channel interference reduction, the process gain, and the BER versus signal to narrow‐band interference ratio have been considered. Simulation results and prototype testing are given so as to illustrate the results obtained with this technique.
