“…PLC channel is classified as a harsh communication channel that exhibits time varying characteristic and hence is difficult to model. Even though there exists no standard PLC channel model, the indoor as well as outdoor powerline channel are in general considered to be multipath frequency selective channel [3].…”

“…Powerlines are accessible even in very remote locations, and offer a "No New Wires" solution to the last mile connectivity problem. However, powerlines are observed as a harsh communication channel, which is plagued by various types of noise [3]. Due to such characteristics, adoption of PLC channel as a broadband data network for high data rate communication has Sabia Baig is with Electrical Engineering Department, COMSATS Institute of Information Technology, Lahore, Pakistan (Email: -drsobia@ciitlahore.edu.pk).…”

Abstract-Powerline communications (PLC) are receiving special attention since they use an already available and ubiquitous infrastructure. The main standard for PLC home networks is HomePlug. This work improves the throughput of HomePlug by modifying the medium access control sub-layer. The key idea is to define a fast collision avoidance mechanism where every station that wants to access the medium increments its contention window after sensing another ongoing transmission. The proposal reduces the number of collisions in the network improving the achievable throughput. We compared our mechanism to the original HomePlug standard through simulation and mathematical analysis. We verified that the improvement is independent from the packet size, the transmission rate and the number of nodes when the network is high loaded.

“…On the other hand, PLC channel constitute a rather hostile medium for data transmission; particularly, it is characterized by frequency selective phenomena, echoes, colored noise, narrow band interference and impulsive noise. This challenging environment claims for highly sophisticated communications techniques [2]. Different communication systems have been proposed for broadband downstream Power-Line Communications (PLCs) [3]: particularly, Discrete Multi Tone (DMT) techniques have proved to be the proper solution due to their capabilities in facing channel impairments, while affording high capacity.…”

Abstract-This paper deals with a variable rate Discrete Multi-tone Modulation (DMT) system for broadband PowerLine Communications (PLCs), based on the bit-loading algorithm proposed by Leke and Cioffi. In the proposed system a suitable LMS channel estimator is considered, which is based on the insertion of a Training Sequence (TS). The proposed approach will be compared with the ideal channel estimates, showing its effectiveness. Moreover, different TS lengths will be compared. The performance of the system, expressed in terms of Bit-Rate and Bit Error Rate (BER), with and without an estimation error is derived by simulation under the assumption of frequency-selective multipath fading channel and additive colored Gaussian noise, according to the inbuilding networks model.
