发明名称 CONTROL OF BEAM AND FORMATION OF BEAM FOR WIDEBAND MBMB/MBOB-SYSTEMS
摘要 FIELD: communication engineering. ^ SUBSTANCE: in method of data processing for transmission along wideband multi-input channel control vector is obtained for every one from subranges row. Depending on how control vectors are defined, for every subrange control or formation of beam may be realised. Full transmitted power is distributed along subranges on the basis of specific pattern of power distribution, for instance, full inversion of channels, selective inversion, channels of stream filling or even distribution. Then scaling coefficient value is obtained for every subrange on the basis of transmitted power provided for it. Data that is subject to transmission is coded and modulated for provision of modulation symbols. Modulation symbols that are subject to transmission in every subrange are scaled with application of scaling coefficient value for subrange and is additionally transformed with application of control vector for subrange. Then stream of preliminarily converted symbols is formed for every transmitting antenna. ^ EFFECT: improvement of working characteristics with unfavorable channel conditions. ^ 27 cl, 5 dwg
