Massive MIMO With Dual-Polarized Antennas
IEEE Transactions on Wireless Communications, 2023 This paper considers a single-cell massive MIMO (multiple-input multiple-output) system with dual-polarized antennas at both the base station and users. We study a channel model that includes the key practical aspects that arise when utilizing dual-polarization: channel cross-polar discrimination (XPD) and cross-polar correlations (XPC) at the ...

On C-Band Quad-Polarized Synthetic Aperture Radar Properties of Ocean Surface Currents
Remote Sensing, 2019 We present new results for ocean surface current signatures in dual co- and cross-polarized synthetic aperture radar (SAR) images. C-band RADARSAT-2 quad-polarized SAR ocean scenes are decomposed into resonant Bragg scattering from regular (non-breaking)
