Abstract: While many questions still surround the creation and deployment of the smart grid, the need for a reliable communications infrastructure is indisputable. Developers of the IEEE 1901.2 ...

Radio spectrum is pricey. Operators drop billions at auction to lock down licensed frequency bands, and every single ...

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

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 ...

Since the beginning of telecommunications in the early 20th century, telcom carriers and broadcasters have striven to transmit as much information as possible while conserving the limited bandwidth of ...
