Patent number: 10090971Abstract: Various embodiments provide for systems and methods for signal conversion of one modulated signal to another modulated signal using demodulation and then re-modulation. According to some embodiments, a signal receiving system may comprise an I/Q demodulator that demodulates a first modulated signal to an in-phase (“I”) signal and a quadrature (“Q”) signal, an I/Q signal adjustor that adaptively adjusts the Q signal to increase the signal-to-noise ratio (SNR) of a transitory signal that is based on a second modulated signal, and an I/Q modulator that modulates the I signal and the adjusted Q signal to the second modulated signal. To increase the SNR, the Q signal may be adjusted based on a calculated error determined for the transitory signal during demodulation by a demodulator downstream from the I/Q modulator.Type: GrantFiled: November 7, 2017Date of Patent: October 2, 2018Assignee: Aviat U.S., Inc.Inventors: Emerick Vann, Yen-Fang Chao, Youming Qin, Roland Matian

Patent number: 9923647Abstract: A method for enabling confirmation of expected phase shifts of radio frequency (RF) signals emitted from respective elements of an antenna array, such as a phased array antenna used for providing directional RF signal radiation patterns needed for beamforming. As a RF signal transmitted via an antenna element of the antenna array is shifted, e.g., stepped, in phase, the resulting received RF signal is monitored. Following detection of a phase shift, a sample of the received RF signal is captured and stored, e.g., for subsequent analysis, such as comparison with one or more expected signal phase differences to characterize the directivity of the transmitted signal.Type: GrantFiled: December 16, 2016Date of Patent: March 20, 2018Assignee: LitePoint CorporationInventors: Christian Volf Olgaard, Zhiyong Huang, Yen-Fang Chao, Roman Schilter, Stefan Kildegaard Klukowski
