    Abstract: A receiver with orthogonal beam forming technique is achieved that is capable of differentiating different signal components within the received composite signal. An adaptive processor is used to eliminate the signal component whose phase information is known or can be calculated. The phase information of the major component of a signal can be easily acquired by using a limiter. The phase information of other signal components can be acquired by their direction information and other characteristics, such as modulation scheme, etc. Multiple orthogonal beams can be formed by eliminating one unwanted signal component each time by the adaptive processor until all unwanted signal is eliminated. Thus, a composite signal from multiple sources can be broken down into their component signals.

  • Patent number: 10085200
    Abstract: A radio communication route enables communication from an originating ground station to a destination ground station via one of multiple randomly orbiting satellites with no active attitude control. The ground stations and satellites include multi-feed parabolic antennas for receiving radio signals from and transmitting radio signals in multiple directions. The satellites store an address of a destination ground station from which an initial information signal is transmitted and antenna information identifying the satellite antenna feed on which the initial information signal was received. Plural satellite antennas transmit linking information identifying the satellite to the originating ground station.

  • Patent number: 10048348
    Abstract: Apparatus and methods for calibrating tester channels of an automated test system. A relay matrix assembly including a plurality of microelectromechanical (MEM) switches may be used to connect a plurality of tester channels to an analyzer calibration instrument rapidly without requiring serial, robotic probing of the test channels. The relay matrix assembly may be constructed on a printed circuit board that can be attached to an interface on the tester. Calibration parameters for the test channels may be calculated from waveforms received through the relay matrix assembly and that have been corrected to remove waveform distortion introduced by the relay matrix assembly. Parameters to correct for distortion in the relay matrix assembly may be measured in advance and stored for use when calibration is to be performed.

  • Patent number: 10003129
    Abstract: An apparatus consisting of hierarchically elaborated antenna modules is calibrated by steps. Although the AWV can be calculated mathematically based on the required phase shift values of each antenna element for a beam direction to compensate for signal delay. However, in practice, due to hardware implementation imperfection, coupling in signal path for each antenna element within hardware, inaccuracies of implementations, physical misalignment, the mathematically generated AWV does not necessarily provide alignment between transmit beam and receive beam. This subset is sufficient is all practical operation. The subset of AWVs are typically called codebook and the receiver beam points to different direction by using a AWV within the codebook.
