We propose a simple PAM-based coded modulation scheme that overcomes two major constraints of power-line channels, viz., severe insertion-loss and impulsive noise.The scheme combines low-density parity-check (LDPC) codes, along with cyclic randomerror and burst-error correction codes to achieve high spectral efficiency, low decoding complexity, and a high degree of immunity to impulse noise. To achieve good performance in the presence of inter-symbol interference (ISI) on static or slowly timevarying channels, the proposed coset-coding is employed in conjunction with TomlinsonHarashima precoding and spectral shaping at the transmitter. In Gaussian noise, the scheme performs within 2 dB of un-shaped channel capacity (the sphere-bound) at a BER of 10 −11 , even with simple regular LDPC codes of modest length (1000-2000 bits). To mitigate errors due to impulse noise (a combination of synchronous and asynchronous impulses), a multi-stage interleaver is proposed, each stage tailored to the error-correcting property of each layer of the coset decomposition. In the presence of residual ISI, colored Gaussian noise, as well as severe synchronous and asynchronous impulse noise, the gap to Shannon-capacity of the scheme to a Gaussian-noise-only channel is 5.5 dB at a BER of 10 −7 .

Abstract-High rate transmission over power lines imposes stringent requirements in coding and equalization, the chief impairments being severe signal attenuation and impulsive noise. Yet, transmission requirements over this medium have reached several Mbit/sec to compete with other types of access. In this paper, we propose a novel PAMbased coded modulation scheme that is well suited to meeting such constraints. The proposed scheme combines Low Density Parity Check (LDPC) codes and maximum-distance separable block codes to achieve high spectral efficiency, low decoding complexity, and a high degree of immunity to impulse noise. To achieve better immunity to burst and impulse noise, a novel interleaving scheme is proposed. To achieve good performance in the presence of inter-symbol interference, the proposed coset-coding is combined with Tomlinson-Harashima precoding and spectral shaping at the transmitter.

“…In fact, many researchers have focused their efforts on deriving suitable noise models [22], [30]- [36]. Despite the significant efforts towards modeling of BPL noise in the 3-88MHz frequency range, a simple, but yet accurate and universal model is not still widely acceptable [37]- [40]. Anyway, 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].…”

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.
