| Summary: With the development of vehicle technology, the increasing number of equipment and sensors causes weight problems in vehicles. The use of Power Line Communication (PLC) systems in In-Vehicle direct current lines eliminates the weight and cost problems caused by communication cables and does not require external frequency allocation as a wired method. Besides transmission lines, PLC systems are shown as an alternative to In-Vehicle communication methods.
In this study, the impulsive noise, which significantly reduces the performance of In-Vehicle PLC systems, is mitigate by Orthogonal Frequency Division Multiplexing (OFDM) based methods. To mitigate impulsive noise, methods using null subcarrier and data subcarrier are simulated together with blanking-clipping methods in the literature. In the study, noise mitigation methods by subtracting the noise signal obtained by using null and data subcarriers from the received signal are compared with the methods that mitigate noise using blanking-clipping or both. |
