Local Utility Power Line Communications in the 3–500 kHz Band: Channel Impairments, Noise, and Standards
TL;DR: Signal processing approaches to model channel impairments and impulsive noise and mitigate their effects in narrowband PLC systems are reviewed and ways to improve the communication performance based on current and emerging standards are examined.

TL;DR: A cyclostationary model is proposed for the dominant component of additive non-Gaussian noise in PLC additive noise modeling, and it is found that the period in the cyclostATIONary model matched half of the period of the main powerline frequency, which is consistent with previous work in indoor PLC additives noise modeling.

Optimal and Successive Approaches to Signal Design for Multiple Antenna Physical Layer Multicasting
TL;DR: This paper develops a simple successive algorithm to determine the covariance matrix of the signal vector under the assumption that channel state information (CSI) is perfectly available at the transmitter and proposes a successive beamforming algorithm that generates the beamforming vector with low computational complexity.
