“…The idea is to train a neural-network to project the noise time series in an appropriate latent space where the features can be extracted and used to classify the noise. In general, the exploitation of machine learning techniques can consistently aid the process of classification and the detection of noise classes in real noise scenarios [20], [32].…”

“…The noise in a MCO power line, in addition to the classes mentioned earlier, may manifest similar characteristics between different conductor pairs. An example is the high spatial correlation between the cyclostationary noise signals on different line phases, usually caused by network-based switched power supplies [32]. Moreover, measurements demonstrate that MCO noise is not only correlated but sometimes reveals deterministic behaviors [29].…”

Several experiments and field trials have shown that deterministic components characterize the Power Line Communication (PLC) noise across multiple-conductors. This article aims at understanding the main origins of these noise components and evaluate several methods to characterize them statistically. The correlation, distance-correlation, mutual information estimation, and a proposed linear coefficient ratio, are used to analyze the noise time-series statistically. The analysis of the PLC noise deterministic components allow us to develop an enhanced noise model that includes them. The presence of deterministic noise fosters the development of coding and decoding algorithms that aim at mitigating the noise effect. New decoding techniques called Quasi-Deterministic-Decoding are detailed and tested with single-input-multiple-output (SIMO) 1x2 and multiple-input-multiple-output (MIMO) 2x2 transmission configurations using real PLC noise and channel realizations. The proposed model leads to a better representation of the PLC noise traces and, consequently, the development of improved coding algorithms for reliable data transmission at low signal-to-noise ratios.

“…In [66], receiver strategies for CS noise reduction by using the FRESH filter approach are explained, they are applied to low SNR NB-PLC systems that implement OFDM. In [67], an improvement of the previous technique for CS noise mitigation designed with estimators also based on the FRESH filtering is discussed, with focus on PLC receivers of systems with single-input multiple-output.…”

This paper provides a comprehensive discussion about the characteristics of power line communication (PLC) channels related to its synchronization with the mains period. This fact constitutes an interesting and distinguishing feature of these kind of channels. Under the mains voltage presence, the behavior of some loads connected to the power network allows representing the transmission medium as a linear periodically time varying (LPTV) system. Some components in the received noise exhibit periodicity as well, in terms of impulsive waveforms synchronized with the mains period and other cyclostationary (CS) signals. This fact has been taken into account in the design of PLC systems, for instance by defining medium access control (MAC) frames synchronized with the mains period and by adapting the modulation to the cyclic signal-to-noise ratio (SNR) to improve the system performance. Hence, in PLC, it is of particular interest to describe the general relations of LPTV systems and CS signals when both have a common period, which is the purpose of this work. It is not aimed at providing new mathematical tools for the analysis of these cyclic signals and systems, which have been extensively developed over the last five decades, but to serve the readers of the PLC community more accessible mathematical relations that can be applied to the practical problems they have to face. A review of recent works dealing with the cyclic properties of PLC channels and transmission techniques aware of these strategies is included as well.INDEX TERMS Cyclostationary random signals, time-varying systems, LPTV, power line communications.

This paper addresses the problem of direction-of-arrival (DOA) estimation for cyclostationary signals using less reception channel in comparison with the number of sensors. The system is considered to be realized by using the reception channel(s) to receive the signal reached each sensor in turn. Such simplification results in a cost reduction of the system and the effect of inconsistency among different channels are removed. However, non-synchronized sampling also makes the traditional DOA estimation algorithms ineffective. To cope with the problem, the signal models for DOA estimation using a single channel and dual channels are formulated based on signal cyclostationary, and the single channel cyclic MUSIC (SC-Cyclic-MUSIC) algorithm and the dual channels cyclic MUSIC (DC-Cyclic-MUSIC) algorithm are proposed correspondingly. This paper shows that both SC-Cyclic-MUSIC algorithm and DC-Cyclic-MUSIC algorithm work well when the switching interval is known, and a satisfied performance can also be obtained by DC-Cyclic-MUSIC algorithm when the uncertainty of the switching interval exists. Moreover, the proposed estimators are suitable for both narrow-band and wide-band signals. The computer simulations are provided to verify the effectiveness of the proposed algorithms. INDEX TERMS Direction-of-arrival (DOA) estimation, cyclostationarity, single channel cyclic MUSIC algorithm, dual channels cyclic MUSIC algorithm.
