DEVICE FOR WIRELESS DUPLEX COMMUNICATION WITH FREQUENCY DIVISION USING AN INTELLIGENT ANTENNA Russian patent published in 2007 - IPC H04Q7/20 

Abstract RU 2302708 C2

FIELD: possible use in multi-station access mobile communication systems with frequency division.

SUBSTANCE: wireless base station contains transmitting and receiving antenna arrays and, respectively connected to them, transmitters of radio frequency channels and receivers of radio frequency signals, and also common block for processing group signals. Group signal processing blocks for respectively the uplink and the downlink, included in common processing block, and connected respectively to receivers and transmitters by means of data bus, use common synchronization and frequency generation block and provide production of values of estimate of signal arrival direction on basis of signal received through the uplink, determining of direction of main route of signal received through the uplink on basis of aforementioned signal arrival direction evaluation values and creation of beam for the downlink with usage of main signal route direction.

EFFECT: creation of wireless duplex communication device with frequency device using an intelligent antenna, making it possible to overcome limitations caused by asymmetry of characteristics of the downlink and the uplink.
