A Video Processing Based LiFi System using Morse Code based Modulation

With an increase in demand for high speed communication networks and also a need for superior security, there has been a huge spurt in discovering newer communication methodologies over the past few years. Among these Light Fidelity or LiFi has gained great prominence especially when the need arises for short distance and local intranet communication. In this paper a novel methodology for performing LiFi communication has been described wherein a video processing approach has been adopted to receive data unlike previously, wherein photo detectors were deployed. Also, a new method of modulation using Morse code has been elaborated which results in a faster decoding rate and also lowers the need for a large transmission bandwidth. The method elaborated in this paper gives a maximum speed improvement of almost 48 times as opposed to previous state of art technologies. All experiments were conducted using the software MATLAB 2013a.
