Simulation of models and algorithms for wireless communication systems
… models and algorithms for wireless communication systems. The simulations are developed using graphical MATLAB interfaces, and cover the fundamentals of wireless channel modeling, the advantages and limitations of antenna beamforming in multiuser systems, and the underlying principles of OFDM. The …

Information-theoretic analysis of human-machine mixed systems
… such as crowdsourcing and social decision-making systems are designed based on (near-)optimal information processing techniques for machines. However, in such applications, some parts of systems that process information are humans and so systems are affected by bounded rationality of human …

Multi-layered Space Frequency Time Codes
… on multiple-input multiple-output (MIMO) systems. The first studies and compares decoding algorithms for multi-layered space time coded (MLSTC) systems. These are single user systems that combine spatial multiplexing and transmit diversity. Each layer consists of a space time code. The …

Capacity, coding and interference cancellation in multiuser multicarrier wireless communications systems
Multicarrier modulation and multiuser systems have generated a great deal of research during the last decade. Orthogonal Frequency Division Multiplexing (OFDM) is a multicarrier modulation generated with the inverse Discrete Fourier Transform, which has been adopted for standards in wireless and …

System Design and Performance Study for Wireless Information and Energy Transfer in the Internet of Things
… system designs. We study point-to-point WIET systems with bidirectional communication. Multiple-input multiple-output (MIMO) with antenna switching (AS) and beamforming are investigated to improve the achieved downlink-uplink rate region in such systems. An optimal and a low-complexity …
