Analysis of the performance of G3 power line communication synchronisation

The new generation of narrowband Power Line Communication (PLC) standards, notably PRIME and G3-PLC, take different approaches to time synchronisation. This paper presents a detailed performance analysis of G3-PLC’s novel approach, with a focus on the performance in the Additive White Gaussian Noise (AWGN) channel. The paper goes on to suggest modifications to the algorithm to enable better performance on the hostile power line channel. The methodology used is based on bespoke models of the synchronisation algorithms, coded in the MATLAB programming language, providing scope for probabilistic studies under different conditions
