Patent number: 9800316Abstract: Devices and methods are provided for directionally receiving and/or transmitting acoustic waves and/or radio waves for use in applications such as wireless communications systems and/or radar. High directional gain and spatial selectivity are achieved while employing an array of receiving antennas that is small as measured in units of the wavelength of radio waves being received or transmitted, especially in the case of spatially oversampled arrays. Frequency/wavenumber, multi-dimensional spectrum analysis, as well as one-dimensional frequency spectrum analysis can be performed.Type: GrantFiled: May 16, 2016Date of Patent: October 24, 2017Assignee: Hobbit Wave, Inc.Inventor: Harvey C. Woodsum

Publication number: 20170111083Abstract: In a direct sequence spread-spectrum (DSSS) systems, such as CDMA, information is encoded in symbols using phase shift keying or quadrature amplitude modulation. Further, a transmitter applied a selected time shifted lag to each symbol to convey additional information. A receiver detects both the symbol data and the lag value. The receiver can use a hermetic matched filter matrix to identify the lag.Type: ApplicationFiled: December 23, 2016Publication date: April 20, 2017Applicant: Hobbit Wave, Inc.Inventor: Harvey C. WOODSUM
