Throughput 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 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...

اندیشمندان و صاحب نظران علوم اجتماعی بر این باورند که مرحله تازه ای در تاریخ جوامع بشری اغاز شده است. ویژگیهای این جامعه نو را می توان پدیده هایی از جمله اقتصاد اطلاعاتی جهانی ، هندسه متغیر شبکه ای، فرهنگ مجاز واقعی ، توسعه حیرت انگیز فناوری های دیجیتال، خدمات پیوسته و نیز فشردگی زمان و مکان برشمرد. از سوی دیگر قدرت به عنوان موضوع اصلی علم سیاست جایگاه مهمی در روابط انسانی دارد، قدرت و بازتولید...
15 صفحه اولPower 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 کاملComparison of ConvOFDM and Wavelet–OFDM for Narrow–Band Power Line Communications
Systems for Power Line Communications (PLC) mostly apply multicarrier modulations in order to cope with the time dispersive nature of the power line transmission channel. In the emerging IEEE 1901.1 standard on broad–band communications via power line, two alternative techniques, conventional OFDM (convOFDM) and Wavelet–OFDM, are included. However, up to now, only convOFDM systems can be found ...
