  • Patent number: 9088388
    Abstract: The high quality PCS communications are enabled in environments where adjacent PCS service bands operate with out-of-band harmonics that would otherwise interfere with the system's operation. The highly bandwidth-efficient communications method combines a form of time division duplex (TDD), frequency division duplex (FDD), time division multiple access (TDMA), orthogonal frequency division multiplexing (OFDM), spatial diversity, and polarization diversity in various unique combinations. The method provides excellent fade resistance. The method enables changing a user's available bandwidth on demand by assigning additional TDMA slots during the user's session.

  • Patent number: 6845243
    Abstract: The composition of an object within a wireless communication channel is determined by analyzing a symmetry characteristic of a polarization pattern of a received signal. The signal is transmitted through the communication channel using a known polarization. A receiver receives the signal and determines a symmetry characteristic of the polarization pattern of the received signal. The symmetry characteristic is matched to a stored symmetry characteristic to determine the composition of the object. Based on the composition of the object, the susceptibility of the wireless communication channel to wind-induced fading can be determined.

  • Patent number: 4990918
    Abstract: A radar reflector provides an enhanced radar cross section pattern in one plane and this improved radar detectability in that plane. The radar reflector comprising a trihedral corner reflector arrangement having three planar faces at right angles to each other, a first planar face substantially triangular in shape having a right angle representing a common vertex, second and third planar faces joined at inner edges of the second and third planar faces to form a center line extending from the common vertex and each joined to the first planar face at straight sides extending from the common vertex such that the reflector is symmetrical about the center line, the center line being shorter than the two straight sides.
