  • Patent number: 7805144
    Abstract: Channels are assigned based on co-spatial constraints in wireless network using spatial division multiple access. In one example, the invention includes assigning a co-spatial constraint to each of a plurality of conventional traffic communications channels of a base station, and receiving a request from a user terminal to communicate using a traffic communication channel of the base station. The invention further includes measuring a quality parameter of the request deriving a co-spatial constraint for the user terminal, assigning the user terminal co-spatial constraint to the user terminal, and assigning the user terminal to a traffic communication channels having a channel co-spatial constraint that is no less than the user terminal co-spatial constraint and that has no more assigned radios than permitted by the channel co-spatial constraint.

  • Patent number: 7539496
    Abstract: The present invention can improve efficiency in wireless radio networks using spatial division multiple access (SDMA) strategies. One embodiment of the invention includes determining a quality parameter of a user terminal based on a signal received from the user terminal at a base station. One embodiment further includes determining a co-spatial constraint on the user terminal based on the quality parameter, the co-spatial constraint comprising a limitation on the quantity of additional user terminals with which the user terminal can share a conventional communications channel.

  • Publication number: 20070209057
    Abstract: A device for wireless, non-line-of-sight delivery of a signal from a coaxial cable to a transceiver at an end user device comprises a signal enhancement and prioritizing module which converts the signal into a wireless signal which comprises less data than the signal, and an antenna which broadcasts the wireless signal to at least one end user device transceiver, wherein the wireless signal has the capability to transfer data to the at least one end user transceiver at a rate of greater than 40 Mbit per second.

  • Patent number: 7054301
    Abstract: The present invention allows many of the benefits of spatial diversity to be realized in a hopping radio communications system. One embodiment of the invention includes transmitting signals from a first radio using a first hopping sequence and transmitting signals from a second radio using spatial processing and a second hopping sequence. The second hopping sequence is coordinated with the first hopping sequence. In another embodiment, the invention includes selecting a set of spatial processing parameters based, at least in part, on a determination whether a third radio using a first frequency resource during a first time interval uses a second frequency resource during a second time interval and transmitting a signal from a first radio to a second radio during the second time interval using the second frequency resource and the selected set of spatial processing parameters.

  • Patent number: 7010022
    Abstract: The spread spectrum receiver employs circuits based on direct conversion techniques. These circuits enable realization of spread spectrum receivers of greatly reduced complexity and of much higher chip rates that can be implemented with the standard approach of a fully digital receiver. With these circuits, the digital processing is performed at the data symbol rate and not at a multiple of the chip rate that is customary in state-of-the art spread spectrum and CDMA receiver design.

    Abstract: The spread spectrum receiver employs circuit 21, 31, etc. based on direct conversion techniques. These circuits enable realization of spread spectrum receivers of greatly reduced complexity and of much higher chip rates than can be implemented with the standard approach of a fully digital receiver. With these circuits, the digital processing at the receiver is performed at the data symbol rate and not at a multiple of the chip rate that is customary in state-of-the art spread spectrum and CDMA receiver design.

  • Patent number: 5832044
    Abstract: The present invention provides a bandwidth-efficient fading-resistant transmission scheme where a base station implements transmitter diversity using L antennas or L carrier frequencies or L time slots, regardless of the use of frame oriented power control. When the antennas or carriers are spaced sufficiently far apart, or when a different power is used for each power control frame, the transmission from each antenna or carrier or time frame undergoes independent fading. These transmissions are coordinated to mitigate the effects of Rayleigh fading and the mobile receiver can recover the entire L-dimensional transmitted vector as long as the signal energy of at least one coordinate is large enough. L-dimensional fading-resistant signal constellations are generated by maximizing a figure of merit for the Rayleigh fading channel. This scheme offers a significant performance improvement over a conventional single-antenna or single-carrier narrowband BPSK scheme when coding is ineffective due to slow fading.
