Abstract

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.

Abstract

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.

IPC Classes  ?

  • H04B 1/707 - Spread spectrum techniques using direct sequence modulation
  • H04B 1/7093 - Matched filter type
  • H04B 1/7095 - Sliding correlator type
  • H04B 1/7103 - Interference-related aspects the interference being multiple access interference

Devices and methods using the hermetic transform for transmitting and receiving signals using OFDM

Abstract

Systems and methods are described using a Hermetic Transform and inverse Hermetic Transform for transmitting and receiving a signal with multiple subcarriers, oversampling the received signal, and providing the resulting signals to a Hermetic Transform to provide a higher resolution output signal. An inverse Hermetic Transform is used to process data for transmission. The result is comparable to a form of OFDM that has orthogonality in a minimum norm/least-squares sense.
