Information Theoretic Analysis of a Dual-Band MIMO Cellphone Antenna with ANSYS HFSS SBR+
Volodymyr Shyianov, Bamelak Tadele, Vladimir I. Okhmatovski +1
Historically, the design of antenna arrays has evolved separately from Shannon theory. Shannon theory adopts a probabilistic approach in the design of communication systems, while…
Lens-Type Redirective Intelligent Surfaces for Multi-User MIMO Communication
Bamelak Tadele, Faouzi Bellili, Amine Mezghani +2
This paper explores the idea of using redirective reconfigurable intelligent surfaces (RedRIS) to overcome many of the challenges associated with the conventional reflective RIS. W…
Channel Estimation for Multicarrier Systems with Tightly-Coupled Broadband Arrays
Bamelak Tadele, Volodymyr Shyianov, Faouzi Bellili +1
This paper develops a linear minimum mean-square error (LMMSE) channel estimator for single and multicarrier systems that takes advantage of the mutual coupling in antenna arrays.…
Age-Limited Capacity of Massive MIMO
Bamelak Tadele, Volodymyr Shyianov, Faouzi Bellili +2
We investigate the age-limited capacity of the Gaussian many channel with total users, out of which a random subset of users are active in any transmission period, and…
