The computational complexity and the power consumption of Channel State Information (CSI) acquisition are important drawbacks in wireless communication systems. Focusing on the special case of the IEEE 802.11p standard for wireless access in vehicular environments, this paper proposes an strategy to reduce the computational complexity associated to the CSI acquisition by including a decision rule...
A design of a receiving 4x1 element phased antenna array based on Mutually Coupled Third Harmonic Self-Oscillating Mixers has been presented. The use of the third harmonic of the self-oscillation allows higher beam steering angles without extra circuitry showing the potential these multifunctional circuits have. The experimental behavior obtained with the receiving phased antenna array has been compared...
A novel agile antenna based on an injection-locked third harmonic self-oscillating mixer is presented in this paper. The phase-shift can be tuned, by varying the varactor control voltage, in range of 450deg. The active circuit allows changing the axial ratio of a dual-polarization antenna. The antenna can switch between radiating RHCP, LHCP and linear polarization with good purity.
