Abstract  Abstract

(57) (Summary) A wireless communication system combines time diversity and space diversity to reduce fading and simplify a receiver configuration. More specifically, data packets carrying digital telephone traffic are transmitted from three different antennas at three different times. Thus, the mobile subscriber unit receiver receives the same data packet from three different antennas at three different times and uses the best data packet or a combination of these data packets to reduce the effects of fading. The transfer station receives a time division multiple access (TDMA) signal from a base station carrying telephone data packets and forms three data packet repetitions at spatially distinct antenna locations. The transfer station also modulates a code division multiple access (CDMA) sequence using a TDMA signal that forms a link between the mobile station subscriber and the transfer station. Thus, each data packet received by the transfer station is transmitted to the mobile station subscriber via the CDMA link at three different times. In one embodiment, each transmitting station has three space diversity antennas. The second embodiment uses three transfer stations, each having one spatially distinct antenna. The time division multiplexed and code division multiplexed signals transmitted from the space diversity antenna allow for subscriber station location measurements using the same signal for main telephone data communications. In particular, the subscriber station receiver uses the absolute and relative arrival times of the three repetitive data packets to calculate the respective distance to the mobile subscriber station or the three transmitting antennas. Since the transmitting antennas are at known fixed positions, the position of the receiver is determined.
