Abstract
Extending the analysis already presented in [1], this paper considers broadband potential of overhead (OV) transmission multiple-input multiple-output (MIMO) broadband over power lines (BPL) networks when different noise conditions occur and different well-proven noise models are adopted. The contribution of this paper is two-fold. First, the broadband potential of a great number of indicative OV high-voltage (HV) BPL topologies and of MIMO transmission schemes is studied in terms of appropriate capacity metrics. The relevant numerical results reveal the significant dependence of ΜΙΜΟ capacity metrics on noise conditions. Second, various well-known BPL noise models from the literature are compared on the basis of their achieved OV HV MIMO BPL capacity. Through the careful study of the capacity results of noise models, it is demonstrated that spectrally flat additive white Gaussian noise (AWGN) may be comfortably assumed as an efficient noise model in transmission MIMO BPL networks. Also in MIMO BPL networks, the comparative capacity analysis of noise models shows small differences among them in the 3-88MHz frequency range. Citation ：Lazaropoulos, A. G. (2016).

Highlights
The deployment of broadband over power lines (BPL) networks across the overhead high-voltage (OV HV) power grid is among the first steps towards its modernization
Among the possible configurations for a given full multiple-input multiple-output (MIMO) transmission scheme, only the one with the maximum capacity performance is examined. These considerations do not affect the generality of the following OV HV MIMO BPL capacity analysis, anyway [2], [7]-[12]
Due to the common nature of noise, accurate and simple noise models may play the role of bridge among different SISO and MIMO distribution and transmission BPL networks offering an elementary step towards more coexistence among BPL systems in the oncoming smart grid network [61]-[63]
Summary
The deployment of broadband over power lines (BPL) networks across the overhead high-voltage (OV HV) power grid is among the first steps towards its modernization. As capacity computations are concerned, many BPL researchers tend to use simple but effective noise models that are proven to have realistic, validated with measurements and comparable results in the 3-88MHz frequency range [1], [30], [41]-[43]. Another common practical procedure among BPL engineers is the consideration of spectrally flat additive white Gaussian noise (AWGN) –denoted as FL noise model in this paper– [4], [6], [12], [23], [29], [44].
