Antenna Impedance Estimation in Correlated Rayleigh Fading Channels
Shaohan Wu, Brian Hughes
We formulate antenna impedance estimation in a classical estimation framework under correlated Raleigh fading channels. Based on training sequences of multiple packets, we derive t…
Impedance Variation Detection at MISO Receivers
Shaohan Wu
Techniques have been proposed to estimate unknown antenna impedance due to time-varying near-field loading conditions at multiple-input single-output (MISO) receivers. However, it…
Antenna Impedance Estimation at MIMO Receivers
Shaohan Wu, Brian L. Hughes
This paper considers antenna impedance estimation based on training sequences at MIMO receivers. The goal is to firstly leverage extensive resources available in most wireless syst…
PCA-based Antenna Impedance Estimation in Rayleigh Fading Channels
Shaohan Wu, Brian L. Hughes
Impedance matching between receive antenna and front-end significantly impacts channel capacity in wireless channels. To implement capacity-optimal matching, the receiver must know…
A Hybrid Approach to Joint Estimation of Channel and Antenna impedance
Shaohan Wu, Brian L. Hughes
This paper considers a hybrid approach to joint estimation of channel information and antenna impedance, for single-input, single-output channels. Based on observation of training…
