  • Diversity combining for antennas
    Patent number: 5884192
    Abstract: An antenna configuration increases the sensitivity of a base station by providing a plurality of antennas each of which cover a disjunct or partially disjunct area of a larger cell. A receiver for each antenna receives signals transmitted from mobile stations. Equalizers are attached to each receiver for correcting the received signals. A combiner then combines the received signals from the different antennas so as to form an estimate of the transmitted signal.
