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.

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.

Abstract: A transmitting station for communicating data in a CDMA cellular system that utilizes transmission diversity by transmitting a plurality of PN spread spectrum signals. The transmitting station spreads and modulates the data with a plurality of different PN codes to form a plurality of PN spread spectrum modulated data signals. A transmitter transmits the PN spread spectrum modulated data signals from the transmitting station. Preferably, the transmitter includes multiple spaced apart antennas from which the respective PN spread spectrum modulated data signals are transmitted. Preferably, the transmitter is configured to transmit the PN spread spectrum modulated data signals as a plurality of time slotted PN spread spectrum signals, each PN spread spectrum modulated data signal in a different time slot.

Abstract: A subscriber station for a CDMA cellular system that utilizes transmission diversity by transmitting a plurality of PN spread spectrum signals. Data is transmitted as PN spread spectrum modulated data signals where at least a first PN spread spectrum modulated data signal is formed by spreading and modulating the data with a first PN code and a second PN spread spectrum modulated data signal is formed by spreading and modulating the data with a second PN code which is different than the first PN code. The subscriber station has a receiver which receives the first and second PN spread spectrum modulated data signals. A despreader and demodulator despreads and demodulates the received PN spread spectrum modulated data signal using the respective PN codes. A combiner reconstructs the data from the despread and demodulated data signals.

A receiver sequentially receives at least a first data signal corresponding to the data in a first time slot and a second data signal corresponding to the data in a second time slot. The second time slot occurring after the first time slot so that the data signals are not simultaneously received. A combiner for reconstructs the data from the received data signals.
