Wireless communication technologies are underpinned by the need of increasingly high data rates in a variety of channels ranging from small-scale wireless interconnects to large-scale mobile networks.
The operation of those systems in complex electromagnetics environments makes it difficult to achieve large channel capacities over broad frequency bandwidths.
The signal is affected by system noise and it fades away for large propagation distance, especially in absence of line of sight and in presence of multiple scattering objects. Predicting and overcoming those physics-based capacity limits as well as the effects of noise on multiple input and multiple output (MIMO) systems is the focus of engineering and mathematics on communications.
