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 ...

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 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 ...

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 ...

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 ...

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 ...

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 ...

The head of a new advocacy group determined to free TV broadcasters from government rules mandating 8VSB as the sole DTV modulation scheme authorized for use in the United States has applied for an ...

Even as third generation (3G) wireless equipment continues deployment, the wireless ecosystem is identifying and designing fourth generation (4G) systems. Although there is no clear definition on what ...
