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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

Orthogonal frequency division multiplexing (OFDM) has become attractive for many current and emerging commercial applications because it provides a combination of data throughput, scalability, and ...
