Abstract

In this paper, frequency domain noise measurement and analysis is presented for in-home power line broadband communication. A design measurement system was set up that captured the noise in frequency domain for broadband indoor power line communication. Noise samples were captured with spectrum analyzer in the frequency band from 3 to 30MHz considered to be range of frequencies for in-home power line broadband communications system. The measurement were conducted in residential buildings at Afe Babalola University Nigeria, within months; April, May and early June, 2020. From the measured data, the parameters of the noise measurements in terms of its noise amplitude, noise power level, and power spectral density were examined. Our study confirms and mirror those of the previous findings and contributes additional evidence that suggest considerably that more work will need to be done to mitigate the effects of noise in an indoor PLC environment.
