Over the past several years, orthogonal frequency division multiplexing (OFDM) has received considerable attention from the general wireless community and in particular from the wireless LAN (WLAN) ...

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 ...

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 ...

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 ...

OFDM is a special form of multicarrier modulation (MCM), where a single data stream is transmitted over a number of lower rate subcarriers. It is worth mentioning here that OFDM can be seen as either ...

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 ...

What is OFDMA (orthogonal frequency-division multiple access)? Orthogonal frequency-division multiple access (OFDMA) is a technology of Wi-Fi 6 (802.11ax) that lets access points serve multiple ...
