Capacity Limitation of Small Cell Densification
Sheikh, Muhammad Usman; Lempiäinen, Jukka; Jantti, Riku
International Conference on Information Networking (2022)
conference<p>Deployment of small cells is considered as an easy approach for adding capacity to the system. However, it is important to realize that in a non-noise limited system, each additional cell increases the interference ... -
Direct Path Interference Suppression Requirements for Bistatic Backscatter Communication System
Biswas, Ritayan; Sheikh, Muhammad Usman; Yigitler, Huseyin; Lempiainen, Jukka; Jantti, Riku
IEEE Vehicular Technology Conference (04 / 2021)
conferenceThe ambient backscatter communication (AmBC) system utilizes the existing ambient RF signals present in the atmosphere for backscattering the signal. One of the challenges for AmBC system is the interference at the receiver ... -
Energy Efficiency Maximization of Full-Duplex Two-Way Relay with Non-Ideal Power Amplifiers and Non-Negligible Circuit Power
Cui, Qimei; Zhang, Yuhao; Ni, Wei; Valkama, Mikko; Jantti, Riku (01.09.2017)
article<p>In this paper, we maximize the energy efficiency (EE) of full-duplex (FD) two-way relay (TWR) systems under non-ideal power amplifiers (PAs) and non-negligible transmission-dependent circuit power. We start with ...
