Test and verification of the physical layer of power line communication systems are very difficult to accomplish, because the mains grid exhibits stochastic and time variant behavior. In this paper, we propose a channel emulator that allows for emulating a freely configurable PLC channel scenario in the frequency range between 9 kHz and 500 kHz. The emulator can be deployed for system verification during the design and development phase as well as for standardization purposes.

Transmit signals for low-speed PLC may be seriously obstructed by impulsive noise, resulting in a significant degradation of system performance and reliability. In this paper we provide a possible solution to this problem by using Wavelet Packets for integrated signal modulation and analysis. Moreover we show that Analytic Wavelet Packets which are known for superior signal analysis properties are also suitable for modulation.

OFDM/DMT has been proposed as a suitable modulation for Power-line Communications (PLC). Meanwhile, another modulation, named OFDM/OQAM, was presented to be also an alternative to OFDM. Further, the HS-OQAM system was proposed particularly for the baseband communications such as PLC. This paper gives a theoretical expression of the inter-symbol interference (ISI) plus inter-carrier interference (ICI) power for HS-OQAM system. Moreover, the transmission capacity analysis will lead us to find out who is the winner between these two systems for PLC.

Advanced Metering Infrastructures require reliable communication links. This paper proposes a protocol stack for smart metering based on the parameters of a robust low-speed PLC physical layer. The protocol stack under consideration implements IPv6 on top of a contention-free media access control sub-layer, thereby allowing for maximum flexibility. Simulation results show that this protocol stack allows data transfers at acceptable latencies, despite low data rates at the physical layer.

Broadband Power Line Communications (PLC) technology allows the usage of electrical power supply networks for communications purposes, such as audio/video streaming and broadband internet access. The powerline has an inherent characteristic that is the cyclic variation of channel and noise with the phase of the AC line cycle. To achieve either high throughput or high robustness, we apply dynamic channel adaptation scheme that exploits the cyclic variation of powerline characteristics. In this paper, we introduce an expedient, dynamic channel adaptation which is robust against the short-time variation of the AC synchronized powerline channel and noise. We analyze the performance enhancement for the measured powerline channel and noise when the proposed adaptation scheme is applied to the Korean standard on high speed powerline communications.

In this paper, we present a fast re-synchronization algorithm for permutation coded sequences. The new algorithm combines the dynamic algorithm and a Viterbi-like decoding algorithm for trellis codes. The new algorithm has a polynomial time complexity O(N), where N denotes the length of the sequence. A possible application to M-ary FSK for the CENELEC A band power-line communications (PLC) is considered.

Power line communications (PLC) has become a viable local area network (LAN) solution for in-home networks. PLC systems can be used in a wide variety of applications requiring high data rate. Therefore, there is a need to achieve an extremely high bit rate. In this paper, the increase in current technology bandwidth up to 100 MHz is investigated. Furthermore, a fast computational resource allocation algorithm is also developed for linear precoded discrete multitone (LP-DMT), which enables reliable high bit rate under peak BER constraint. Simulations are run over PLC channels and it is highlighted that 1 Gbit/s transmission is achievable and it is also shown that peak BER constraint algorithms give better performance compared to classical peak SER constraint algorithms. In addition, the linear precoding technique brings significant bit rate gain.

We propose a design method for multicarrier systems based on the achievable rate. We focus on pulse-shaped OFDM, adopted by the HomePlug AV system, and filtered multitone modulation (FMT). For a given sub-channel pulse shape, the number of tones and the interpolation factor can be determined by maximizing a design metric based on the achievable rate. Numerical results and comparisons are reported for typical power line communication (PLC) indoor channels, considering also the problem of notching.

This manuscript discusses the adaptive OFDM system for narrow-band power-line communications with nonwhite and cyclostationary noise environment. The bit and power allocation algorithm is proposed with the considerations on the cyclostationarity of power-line noise. Numerical evaluation shows that the proposed method can improve the average BER performance under PLC noise environment.

This paper investigates multiple emitting/multiple receiving points diversity technique for multi-wire transmission over frequency selective multi-wire channels. To be resilient to the inter-symbol interference (ISI) present in the frequency selective fading, diversity technique must be used in conjunction with wide band multi-carrier modulation (MCM). We introduce an efficient Space-frequency (SF) coded Multi-tone M-ary Multi-level FSK (M3FSK) for indoor communications. Simulation results show that there is up to 5dB performance improvement of the SF over single-wire M3FSK systems in highly impulsive power-line environments.
