Abstract :
Recently the indoor power line has been proposed as a competitive technology for digital systems in homes. Indoor power line integrated with other systems to distributing data inside home, such as visible free space optic (VFSO). Because power line is an unpleasantly medium in case of noise and multipath distortion the existing systems do not have good quality factor. So considerations of these parameters are very important issue to model the actual system. This paper attempts to investigate the performance of decision feedback equalizer (DFE) to reducing the effects of impulsive noise and ISI for integrated between BPLC and VFSO, and comparing the result with system which use Orthogonal Frequency Division Multiplexing (OFDM) techniques. It has been observed that in the case of using DFE based on LMS algorithm the multipath effects and bit error rate are reduced. The information that is presented in this paper could be useful for a optimizing the design of the BPLC systems.
