SFO Estimation Scheme In OFDM-based Power Line Communication System
This paper proposes a efficient blind sampling frequency offset (SFO) estimation technique for an orthogonal frequency division multiplexing (OFDM) based power line communication (PLC) system. The main drawback of the conventional estimators is their limited estimation range and their high sensitivity to effect of SFO. To remedy these, this paper proposes two-step correlation scheme that exploi...
متن کاملHigh-speed Power Line Communication System based on Wavelet OFDM
Recently, the demand of high-speed network in home is increasing. PLC (Power Line Communication) is expected as one method of realizing it. OFDM is one of the methods, which realizes high-speed PLC. But the minimum stopband attenuation of OFDM modulation is only -13dB. It indicates that OFDM subchannels are not spectrally isolated, therefore OFDM is sensitive to the locations of narrow band int...
متن کاملImprovement for LDPC Coded OFDM Communication System over Power Line
Power line communication has been around in past decades and gained renewed attention thanks to the demand of high‐speed Internet access. With the significant advantages of existing infrastructure and accessibility to even remote areas, power grid has become one of the promising competitors for multi‐media transmission in household. However, the power line was not oriente...
متن کاملCommunication System using OFDM on a Power Line Channel
The efficient communication systems development that use like environment of transmission the net of energy (Power Line Communication) needs a detailed knowledge of the channel's estates, such as the capacity, the noise, the setting of interference and the function of transference, currently the OFDM modulation is utilized in power line communication in information transference application with...
متن کاملNarrow Band Interference Reduction in OFDM-based Power Line Communication Systems
Broadband orthogonal frequency division multiplexing (OFDM) communication systems utilizing the low-voltage power supply network are exposed to different types of disturbances, which essentially determine the achievable transmission capacity. Narrow band interference (NBI), that can be caused by switching power supplies as welt as the ingress of short and medium wave radio transmitters located ...
