We describe a transmission scheme combining 4-FSK modulation with diversi&'&d coding to make the transmission over power lines robust against permanent frequency disturbances and impulse noise. We use simple non-coherent detection and derive the corresponding error correcting capabilities of the scheme. Since we use 4-FSK, the scheme is in agreement with the existing CENELEC norms. The scheme c...

In this paper, we present a survey on implementation of adaptive power line interference canceller for ECG signals and recommends Least mean-square (LMS) algorithm for implementation of adaptive power line interference canceller using FPGA. Notch filters and adaptive interference cancellers are proposed in literature for power line interference canceller. Notch filters are ineffective, whenever...

In the TESLA superconducting linear collider project, collisions occur at zero crossing angle. The option to rapidly dump the spent beams after the collision has been favoured recently to avoid the inconveniencies of large beam losses and beam line activation. For these reasons, the design of the beam and beamstrahlung extraction lines must be interplayed with those of the final focus optics an...

A data-driven approach to the performance analysis of wind turbines is presented. Turbine performance is captured with a power curve. The power curves are constructed using historical wind turbine data. Three power curve models are developed, one by the least squares method and the other by the maximum likelihood estimation method. The models are solved by an evolutionary strategy algorithm. Th...

In this work we have designed a system to play remotely high quality multichannel digital audio by the Power Line home network. POLI-MAS solves the needs imposed by the convergence of the three audio segments, namely, home audio, entertaining audio and PC audio. Thus, the stored audio files in a computer can be played in any location within a home by using the power lines as their transport med...

In this paper, we give an overview of the power line communication (PLC) technology. This paper presents an overview of the research, applications, standards and importance of the power line communication. Power line communication is an emerging home network technology that allows consumers to use their already existing wiring system to connect home appliances to each other and to the Internet....

This paper presents a FIR adaptive filter to cancelling interference due to 50 Hz power line in human electroencephalographic (EEG) inspection. An overview of EEG techniques to study brain activity will be outlined. Then, the problem of spurious signal rejection, in this particular handset, shows the meaningfull application of adaptive filter structure. Poles of filter are driven to find an opt...

The classical solutions for collecting data from energy meters, based on human readings, tend to be replaced by modern solutions. Automatic Meter Reading (AMR) is such a modern solution. It means to automatically collect data from different kinds of meters. In this way consumption of water, gas and energy can be remotely measured. An Advanced Metering Infrastructure (AMI) is an AMR infrastructu...

Power lines and their associated networksare not designed for communications use. They are ahostile environment that makes the accurate propagationof communication signals difficult. Noise levels areoften excessive, and cable attenuation at the frequenciesof interest is often very large. Important channelparameters such as impedance and attenuation are timevarying in...

The actual idea of a telephony structure shows a Private Automatic Branch Exchange (PABX) directly controlling a whole communication system. Ringing and caller identification signals, voltage setting for the phone sets among other important parameters all are transmitted using twisted pair cables that have to be installed and distributed along the building. The use of existing indoor power line...
