A generalization of the achievable rate of a MISO system using Bode-Fano wideband matching theory
Nitish Deshpande, Miguel R. Castellanos, Saeed R. Khosravirad +3
Impedance-matching networks affect power transfer from the radio frequency (RF) chains to the antennas. Their design impacts the signal to noise ratio (SNR) and the achievable rate…

A wideband generalization of the near-field region for extremely large phased-arrays
Nitish Deshpande, Miguel R. Castellanos, Saeed R. Khosravirad +3
The narrowband and far-field assumption in conventional wireless system design leads to a mismatch with the optimal beamforming required for wideband and near-field systems. This d…
