Symbol detection using extreme learning machine network for MU‐SIMO systems
IET Communications, Volume 17, Issue 2, Page 183-196, January 2023., 2023 Abstract This paper focuses on symbol detection for a multi‐user single‐input multiple‐output (MU‐SIMO) uplink using supervised machine learning techniques. An extreme learning machine (ELM) is chosen as the equalizer at the receiver end due to its super‐fast learning ability and minimum training error.

Performance evaluation of cognitive relay networks for end user mobile over mixed realistic channels
IET Communications, Volume 17, Issue 2, Page 228-245, January 2023., 2023 Abstract Cognitive relay network is a spectrum dynamic paradigm that exploits the unused portions of the licensed spectrum. This is based on merging both cooperative relaying techniques and cognitive radio network to achieve spectrum efficiency and enhance the overall system performance.

Communication, sensing, computing and energy harvesting in smart cities
IET Smart Cities, Volume 4, Issue 4, Page 265-274, December 2022., 2022 Abstract A smart city provides diverse services based on real‐time data obtained from different devices deployed in urban areas. These devices are largely battery‐powered and widely placed. Therefore, providing continuous energy to these devices and ensuring their efficient sensing and communications are critical for the wide deployment of smart cities.

Multiple-Input Multiple-Output OFDM with Index Modulation [PDF]
IEEE Signal Processing Letters, vol. 22, no. 12, pp. 2259-2263,
2015, 2015 Orthogonal frequency division multiplexing with index modulation (OFDM-IM) is a novel multicarrier transmission technique which has been proposed as an alternative to classical OFDM. The main idea of OFDM-IM is the use of the indices of the active subcarriers in an OFDM system as an additional source of information.
