LoS MIMO-Arrays vs. LoS MIMO-Surfaces
2023 17th European Conference on Antennas and Propagation (EuCAP), 2023 The wireless research community has expressed major interest in the sub-terahertz band for enabling mobile communications in future wireless networks. The sub-terahertz band offers a large amount of available bandwidth and, therefore, the promise to realize wireless communications at optical speeds.

Spatial Multiplexing for MIMO/Massive MIMO
, 2023 In this chapter, we will discuss how to achieve spatial multiplexing in multiple-input multiple-output (MIMO) communications through precoding design, for both traditional small-scale MIMO systems and massive MIMO systems. The mathematical description for MIMO communications will first be introduced, based on which we discuss both block-level precoding

λ–MIMO: Massive MIMO Via Modulo Sampling
IEEE Transactions on Communications, 2023 Massive multiple-input multiple-output (M-MIMO) architecture is the workhorse of modern communication systems. Currently, two fundamental bottlenecks, namely, power consumption and receiver saturation, limit the full potential achievement of this technology.
