  • MIMO systems with independent oscillators and phase noise mitigation method thereof
    Patent number: 10236948
    Abstract: Disclosed is a phase noise mitigation method using a MIMO system in which each antenna has an independent oscillator. The phase noise mitigation method includes: receiving a transmission signal transmitted from a transmitting antenna, through a receiving antenna and an oscillator; estimating multiple parameters for a phase noise of a transmission terminal and a phase noise of a receiving terminal on the basis of a result of mathematical modeling of signals transmitted and received through the MIMO system in which each antenna has an independent oscillator; and mitigating phase noises of the transmission terminal and the receiving terminal which are estimated from the received signal.

  • Multi-effect solar distiller with multiple heat sources
    Patent number: 9884265
    Abstract: The present invention relates to an multi-effect solar distiller with multiple heat sources. More particularly, the present invention relates to an multi-effect solar distiller with multiple heat sources capable of evaporating and distilling sea water using the solar thermal energy, evaporating the sea water using waste heat generated from a power generation facility in addition to the solar thermal energy, evaporating and distilling the sea water even by condensation heat generated at the time of condensing steam, and using a plurality of absorption reflectors to allow non-used sunlight to maximally evaporate the sea water by being reflected from the sea water surface.
