“…PC is not a new study and its usage for power line communications (PLC) was proposed by Vinck and Häring [3]. Afterwards, a number of researches done in this regard have been published [1], [4]- [9], [23]. PC is made up of codewords C τ with non-repetitive symbols from the set Q = {0, 1, .…”

In digital transmission systems that involve pulse amplitude modulation (PAM), channel coding is useful for spectral shaping by concentrating the frequency energy of the transmitted information towards a predetermined range of the frequency spectrum, or making it have low power content at such frequencies, so as to suit the frequency characteristics of the communication channel. We thus present a permutation coding system with injections that can exhibit spectral shaping at rational sub-multiples of the symbol frequency. We also present a mathematical expression that allows for the prediction of low energy positions in the codebook's spectrum. Upper and lower bounds for the low energy spectrum were also determined. Due to the way the injections are introduced, it gives the scheme an advantage of achieving higher symbol rate, when compared with conventional permutation coding systems.

“…For that, the authors use the convolutional codes and the trellises to simplify the construction and the decoding. Permutation coding is used by Ogunyanda et al, 11 in replacement to the convolutional code, to reduce the complexity of the G3‐PLC system 11 . The proposed scheme composed of differential phase shift keying mapping (DPSK) for orthogonal frequency‐division multiplexing (OFDM), a Reed‐Solomon code, and a hybrid permutation code showed to have better performance than the standard's scheme under the NBI and IN.…”

Summary This paper proposes a coded modulation scheme based on frequency shift keying (FSK) modulation and a simple binary permutation code. FSK detection is based on the knowledge of the probability density function (PDF) of the noise and the attenuation of the channel, called FSK “Soft‐Decision” (FSK/SD) detection. We introduce an approximation of the FSK/SD, called FSK “Select Largest” (FSK/SL). We compare the FSK/SL detection with the classical PDF‐based detection techniques, such as FSK/SD and spread‐FSK (SFSK), for both coded and uncoded transmission. As a practical application, we use the power line communication (PLC) channel. We analyze and compare the performances for a narrowband PLC channel with attenuation and impulse noise.

“…These standards typically operate in low‐frequency bands such as the CENELEC bands, ranging from 3 kHz to 148.5 kHz as defined in the EN 50065‐1 standard . Two leading standards in this domain which are often researched are the eRDF G3‐PLC standard and the Ibrerdola PRIME standard, both specifying the physical layer as systems designed around baseband, real‐valued orthogonal frequency‐division multiplexing (OFDM) transmission signals with specific forward‐error correction (FEC) chains.…”

Summary In this paper, an investigation into the behavior of modern narrowband power‐line communication systems when concatenated with both a fountain code named Luby transform code and a combination of nonlinear preprocessing techniques called signal clipping with blanking is presented. The new systems can be used in applications such as the automatic meter reading component of smart grid technology. Testing is performed on a range of systems provided by the G3 standard and the results show that a bit error rate improvement can be achieved with the correct encoder/decoder settings. The recommended settings include an adaptive technique that uses Gaussian elimination for Luby transform code decoding and code rates that depend on the system specifications used. From there, it is shown that a further improvement is achieved when both the Luby transform code and adaptive signal clipping/blanking based on signal power are combined. It is found that these modifications present a complexity trade‐off, which is higher on the receiver side. This added complexity can be well‐tolerated in automatic meter‐reading systems because of the star topology and asymmetric nature of the network, which has a centralized agent acting as a receiver that collects data from various transmitter nodes.
