Highly efficient signal processing for frequency agile power line communications
A modified frequency hopping signaling scheme has recently received a considerable attention by the designers of power line communication systems because of its insensitivity to frequencyselective and time-variant attenuation and high level of interference. In frequency hopping system, the increase of the data rate without increase of the hop rate is possible only if the receiver can detect all...
متن کاملPower Line Communications Based on Ofdm
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...
متن کاملThroughput Analysis for Wavelet OFDM in Broadband Power Line Communications
Windowed orthogonal frequency-division multiplexing (OFDM) and wavelet OFDM have been proposed as medium access techniques for broadband communications over the power line network by the standard IEEE 1901. Windowed OFDM has been extensively researched and employed in different fields of communication, while wavelet OFDM, which has been recently recommended for the first time in a standard, has...
متن کاملA Narrowband Sound Signal Frequency Estimation with Impulsive Noise Filtering
The new stochastic approach of impulsive noise filtering, based on the input sample separation by modified clusterization criterion, is proposed. It is shown that preliminary filtration by the proposed procedure provides robust narrowband sound frequency estimation and eliminates failures of the estimation algorithm caused by the impulsive noise.
متن کاملNew Transceiver Scheme for OFDM-Based Broadband Power Line Communications
Power line communications (PLC), thanks to the widespread availability of power line infrastructure, is considered as a low-cost alternative for data transmission. Power lines, however, remain hostile environments for communication signal propagation. In this paper, we propose a new transceiver scheme for orthogonal frequency division multiplexing (OFDM)-based broadband power line communication...
