  • Patent number: 8248988
    Abstract: A plurality of antennas transmit a first spread spectrum signal having an associated code. The first spread spectrum signal is received at the wireless user. For each received first spread spectrum signal, a second spread spectrum signal is transmitted having an associated code having a same phase as that received first spread spectrum signal. The second spread spectrum signals are received at the plurality of antennas. A distance measurement is determined between each antenna and the wireless user based on in part a received timing of the second signals. The wireless user's location is determined based on in part the distance determinations.

  • Patent number: 8130696
    Abstract: An information signal is spread with a first spreading sequence producing a first spread signal for transmission over a first antenna. The information signal is spread with the first spreading sequence producing a second spread signal for transmission over a second antenna. The second antenna is not the first antenna. The relative position of the information signal and the first spreading sequence is different in the second spread signal than the first spread signal.

  • Patent number: 7554964
    Abstract: A cellular system utilizes transmission diversity by transmitting a plurality time slotted signals for communicating data. A transmitting station including a transmitter configured to transmit a plurality of data signals corresponding to the data in different time slots. The time slot occurring at different times so that transmitted data signals are not simultaneously transmitted. A receiving station includes a receiver for sequentially receiving the data signals and a combiner for reconstructing the data from the received data signals. Preferably, the transmitting station has a plurality of spaced apart antennas from which the respective data signals are transmitted. Preferably, the system is a CDMA system where the data signals are transmitted from the transmitting station as a plurality of PN spread spectrum signals which are formed by spreading and modulating the data with different PN codes. The receiving station then reconstructs the data by first despreading and demodulating the received data signals.

  • Patent number: 7463608
    Abstract: A transmitting station for communicating data in a cellular system utilizes transmission diversity by transmitting a plurality of signals. A transmitter is configured to transmit at least a first data signal corresponding to the data in a first time slot and to transmit a second data signal corresponding to the data in a second time slot. The second time slot occurs after the first time slot so that the first and second transmitted data signals are not simultaneously transmitted. Preferably, the transmitter includes a first antenna from which the first data signal is transmitted and a second antenna spaced apart from the first antenna from which the second data signal is transmitted. Where the transmitting station is for a CDMA system, the transmitter is configured to transmit said data signals as PN spread spectrum signals. In such case, an encoder is provided for spreading and modulating the data with PN codes to form the data signals. Preferably, different PN codes are used to form the data signals.

  • Patent number: 6842444
    Abstract: A wireless communication system combines time and space diversity to reduce fading and simplify receiver design. In particular, a data packet which carries digital telephone traffic, is transmitted at three different times from three different antennas. The mobile subscriber receiver thus receives the same data packet at three different times from three different antennas, and uses the best data packet or combination of the data packets to reduce the effects of fading. A transfer station receives a time division multiplex multiple access (TDMA) signal from a base station carrying telephone data packet traffic to form three data packet repeats at spatially diverse antennas locations. The transfer station further modulates a code division multiple access (CDMA) system using a TDMA signal which links the mobile subscriber receiver to the transfer station. Each data packet received at the transfer station is thus retransmitted at three different times to the mobile subscriber station on a CDMA link.
