Characterized by extensive coverage, easy connection and huge application potential, power line carrier communication has gained increasing attention and become a research hotspot in recent years. This paper started by an introduction of the power line carrier communication technology, and then compared it with other networking methods, finally practical power line networking project was propos...

The rapid evolution of mobile communication technologies is making mobile broadband a reality. With over 6 billion cellular connections and the booming of mobile data, mobile broadband leads the technology and service innovation within the domain of information and communication technologies. The thesis deals with performance engineering of mobile broadband. The problems investigated range from...

There has been recent interest in the use of broadband communication networks to implement distributed control systems (DCS). Such systems use a high speed local area network (LAN) to connect smooth dynamical systems (plants) with their computer controllers. DCS have appeared with increasing frequency in process control and power plant supervision[l]. There has been recent interest in packet sw...

Accurate power line channel models are an essential asset for the development of advanced power line communication systems. A physically based power line communication channel model is derived. Elements within a power line network, e.g. line discontinuities, branches, and loads, are modelled as IIR-filters. The transfer function of the overall channel is calculated by concatenating the transfer...

A low power 64-point FFT/IFFT architecture is developed for the application in OFDM based wireless broadband communication system. The proposed architecture satisfies the specifications of IEEE 802.11a and ETSI Bran. The architecture requires 25% multiplication and 86% addition/subtraction operation compared to the conventional Cooley-Tukey approach. This leads to power and area saving as well....

OFDM is a special kind of Multi Carrier modulation technique which forms the basis for 4G Wireless system. OFDM is a key broadband technology that can supports data rates in excess of 100 Mbps that is essential for next generation 4G broadband communication.. Peak To Average Power ratio is one of the serious problems in OFDM technology that is problem of extreme excursions of transmitted signal...
