Index modulation (IM) in orthogonal frequency division multiplexing (OFDM) systems represents a transformative approach in modern communications. This technique utilises the indices of active ...
OFDM is a special case of multi-carrier modulations, which is of great use in various wireless communications, such as DAB, DVB, HDTV, CMMB, TMMB and 802.11a. The OFDM frame structure is similar to ...
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 ...
Have you ever heard terms like modulation scheme, orthoganal frequency division multiplexing (OFDM), or symbol rate and scratched your head? As new wireless standards emerge, we get excited about the ...
With wireless LAN (WLAN) popularity continuing to soar, designers must now begin evolving this to the 5-GHz band. Making this leap will not be easy. The IEEE 802.11a system calls for 5-GHz WLAN ...
The CP-OFDM modulation scheme will have many options. Variable subcarrier spacing (SCS) will be 3.75, 15, 30, 60, 120, 240, 480 kHz with sub-1 GHz of 15 and 30 kHz and sub-6 GHz of 15, 30, and 60 kHz, ...
