Index modulation (IM) in orthogonal frequency division multiplexing (OFDM) systems represents a transformative approach in modern communications. This technique utilises the indices of active ...

Moving wireless local area networks (WLANs) to the 5-GHz band is very appealing because of the leap in data rates from 11 or 22 Mb/s to 54 Mb/s. But, making the leap to 5-GHz also means the use of ...

In powerline communications (PLC), OFDM makes better use of bandwidth than FSK. Fast, reliable, and secure communications are critical for enabling the "energy Internet," an interconnected network of ...

Curtiss-Wright’s E-SOQPSK (Extensible SOQPSK) is a software-configurable, ultra-low-power Wi-Fi modulation scheme. Its waveforms offer some beneficial performance attributes for aeronautical telemetry ...

Orthogonal frequency division multiplexing (OFDM) has often been heralded as one of the key technologies for the evolution of the wireless LAN (WLAN) sector. Just look at both the IEEE 802.11a and 802 ...
