DEVICE AND METHOD FOR BEAMS SHAPING IN CDMA COMMUNICATION SYSTEM Russian patent published in 2009 - IPC H04B7/06 H01Q3/26 H04J13/02 

Abstract RU 2354050 C2

FIELD: physics.

SUBSTANCE: invention is related to device and method for beams shaping in telecommunication system of mobile communication CDMA with application of intellectual antennas technology, using specified device and method, multiple fixed beams are shaped in sector, and multiple fixed beams are used to shape traffic channel with narrow beams and common channel with sector beams in one and the same intellectual antenna system, and problem of phases discrepancy is solved in appropriate channels due to differences in time and temperature oscillations without application of complicated correcting technology. Since fixed beams in some area correlate and interact with each other, or considerably weaken due to correlative summation of space vectors of every fixed beam in process of common channels transfer in CDMA system with multiple antennas, then appropriate ratio is established between power of pilot channel and traffic channel in coverage area, and signal-noise ratio is increased for signals received by mobile communication station. As a result of addition of optical transceivers system between system of the main frequency band and system of radio frequency transceivers (TRX), the main frequency band system services more sectors. Radio frequency unit is located in close proximity to antennas, and consumed power is reduced accordingly.

EFFECT: increased throughput capacity and efficiency of CDMA system with multiple antennas.
