A Semi-hidden Markov modeling of a low complexity FSK-OOK in-house PLC and VLC integration

Abstract

The integration of power line communication (PLC) and visible light communication (VLC) is increasingly receiving a lot of research interest with the advent of (IEEE 1901, ITUT G.9960/61) and IEEE 802.15.7 standards for PLC and VLC respectively. In particular, there is an underlying gain that could be achieved by leveraging the existing ubiquitous power line network infrastructure to render connectivity, while we also exploit the illumination system of power-saving Light Emitting Diodes (LEDs) for wireless data communication. The ubiquitous nature of these two systems makes us belief that VLC can offer a good complementary wireless data transmission technology to the existing In-House PLC in a similar manner broad-band Ethernet connections enjoys the support of Wi-Fi. This paper thus reports an implementation of a low complexity FSK-OOK In-House PLC and VLC Integration, as well as it's Second-Order Semi-Markov Model. The resulting statistical models facilitates the design and evaluation of forward error correcting codes to mitigate burst error occurrences, as well as optimizing the performance of the overall system.

Integrated Broadband Powerline and Visible Light Communication (VLC) using OFDM and Turbo Coding

“…This impulsive noise may cause either bit or burst errors in data transmission power line [6,13,14]. When it comes to narrowband noise, it can be modeled as the output of the bandpass filter driven by the AWGN in the discrete sampling space, which can can also be represented as a low frequency sinusoid [9,12,13], (3) where is the carrier frequency of the interferer, and nnb based on prior research has been found to reach power levels of 30 dB greater than the background noise at frequencies greater than 1 MHz .…”

“…In order to make the Power Line Communication (PLC) based networks more practical by having mobility at the last inch connectivity the VLC can be utilised. The ubiquitous nature and advantages for which these two medium of communication possess can be harnessed, such that VLC is made to offer a good complementary wireless data communication to the existing ubiquitous InHouse PLC channel [12]. The idea of integrating both systems was pioneered by Komine et.al in 2002 [9], which has now been taken advantage of in various applications [1,2].…”

“…This is followed by the raised cosine filter circuit, followed by the demodulator and post equalizer to extract the signal. The integrated PLC and VLC system transmission can be represented by the below equation 6 [12], (6) Where r(t) is the received signal, h(t) PLC channel impulse noise, s(t) transmitted signal and finally n(t) represent the channel noise.…”

“…The Mamba shield developed by Link Sprite has been pre-built with a FSK modulation and is designed to work under 11/240V, 50/60Hz supply [12]. The code was designed to transmit and receive data serially.…”

“…Since its first presentation by Komine and Nakagawa [1], some research focus areas reported in literature regarding the HPV system include, PLC/VLC integration techniques [6]- [8], channel modelling [4], [9], modulation, multi-carrier and multi-user techniques [10]- [14], for achieving a reliable, spectral and energy efficient HPV system.…”
