Abstract

In home digitalization system and Smart Grid power line communication (PLC) plays an important role However this system suffers from time-variant channel and noise among which the influence of multipath fading and random impulse noise (IN) is a key problem Therefore how to reduce the impact of these two unfriendly channel’s environment is the primary issue of the PLC system design Based on the G hn (Gigabit Home Networking) standard for broadband PLC systems this thesis is devoted to design the receiving process which includes signal detection channel estimation and symbol synchronization for the preamble under PLC channels with impulse noise This thesis adopts mathematical derivation and system simulations to compare the system performance of two algorithms namely energy detection and autocorrelation detection to perform signal detection The simulation results show that the energy detection scheme can not only be executed with low complexity but also complete the signal detection in just one preamble and remain more preambles to be used for the channel estimation Hence the energy detection scheme for signal detection is better than the autocorrelation detection which is contrary to generally expected
