Multilevel logic transmission using disparate intensity levels of white light and programmable controllers

This paper analyzes the transmission of a multilevel logic information by assigning a distinct level of Intensity of white light to a specific Byte. The criterion for allocation of Intensities is fed into the programmable transmitter controller. The receiver employs a Photocell to detect the transmitted intensity of white light emitted by an LED. The information at the receiving end is retrieved and processed by the programmable receiver controller. The technique discussed takes into consideration the channel´s behavior and the involvement of noise excursions, thus settling for a unique Look up Table at the receiving end. The programmability of the transmitter and receiver controllers allows adjustment according to the variation in channel´s behavior. The paper uses a normal dust free channel opaque in nature, thus providing a cost effective alternative to Optical Fibers and a loss effective alternative to Copper Wires for short length communication systems.
