An Adaptive Decision Feedback Equalisation For Broadband Powerline Communication System

Power line networks can be used to increase accessibility of broadband communication services in developing countries. Nevertheless, power line networks are affected by stochastic channel alterations triggered by load connection and disconnection, branched line lengths, branches, etc. This impairment affects the implementation of Broadband Power Line Communication (BPLC) system. This paper therefore proposes an Adaptive Decision Feedback Equalisation (ADFE) technique to overcome the stochastic channel changes in powerline communication channels. An appropriate power-line channel model is selected and channel impulse responses are obtained from the selected channel model. The impulse responses are obtained and used for simulation to analysing the the performance of ADFE technique. The ADFE is simulated and then results are analyzed through comparisons with other equalizers in order to examine its performance. Simulation results prove that the adaptive decision feedback equalizer performs better to overcome the effects of stochastic changes in power-line network compared to other techniques.

An internet-of-things system based on powerline technology for pulse oximetry measurements

<p class="Abstract">Internet-of-things (IoT) systems, covering any type of application, are becoming increasingly important. The most important network infrastructure used for the development of IoT applications is the Wi-Fi network, as it is widespread and provides greater freedom during installation. There are cases where the cost of building the Wi-Fi infrastructure or the specific field of use do not justify the adoption of this network standard. The following study proposes the use of the powerline network as an alternative to Wi-Fi for the realisation of IoT systems. An IoT system for the monitoring of pulse oximeter values in a hospital setting will be described and discussed. The novelty of the proposed system is the adoption of powerline communication for the medical environment</p>
