Abstract

In this paper, we present a theoretical study of the dispersion in the optical diffuse infrared channel with complete characterization of the multipath dispersion effect for fixed transmitter and receiver locations. For a NRZ transmitted pulse we obtain the received pulse by modeling the channel impulse response and then an equalizer is employed to eliminate intersymbol interference. We describe a complete realization technique for a filter matched to the equalized pulse shape. The realization technique starts with the time domain specification of the equalized pulse shape and yields a network with a response which closely approximates the response desired. The results indicate the usefulness of the realization technique for determining filters for wireless networks when all that is available is a time domain specification of the received pulse.
