OFDM is a technique used in modern broadband wireless communications systems. To mitigate the effect of dispersive channel distortion in high data rate OFDM systems, CP is introduced to eliminate ...

Over the past year I’ve been writing about potential transmission standards for a nextgeneration broadcast platform (NGBP). The most promising standards are all based on orthogonal frequency division ...

As more high-speed amplifier applications deal with communication systems, wired or wireless, a brief introduction and overview of orthogonal frequency division multiplex (OFDM) is necessary. With a ...

WASHINGTON: A newly formed broadcast group is lobbying federal regulators bent on taking broadcast spectrum for broadband to consider alternatives. The group demonstrated how orthogonal frequency ...

Fig1. The traditional electricity grid is evolving into the Smart Grid. The main criteria for an effective distribution grid lie in the efficient distribution of centrally generated energy to a ...

Several waveforms are being researched as potential candidates for the new non-backwards compatible 5G air interface, spanning a wide range from very simple single carrier to very sophisticated ...

The orthogonal frequency division multiplexing (OFDM) system applies coherent demodulation to achieve high spectral efficiency at a bandwidth cost by the pilot tones. Considering the statistical ...

The contemporary wireless communication system makes full use of the available spectrum by making it possible to adapt to various channel situations. The extremely well-organized multi-carrier ...

Qualcomm Inc. may have gained another small weapon for what could become a huge battle over essential patents on next-generation wireless networks. In a deal announced Monday, Qualcomm agreed to ...
