FIELD: radio engineering, communication.SUBSTANCE: invention discloses a multi-antenna signal processing system. The system consists of: a discrete Fourier transform (DFT) based processing unit, a unit for processing multi-antenna signals and conversion to resource elements, and an inverse fast Fourier transform (IFFT) based processing unit. The system also includes a preliminary transformation unit for preliminary transformation of input data stream(s) based on the current mode of processing multi-antenna signals and outputting pre-transformed data stream(s) to the processing DFT unit.EFFECT: high diversity factor and multiplexing factor, relatively low peak power-to-mean power ratio in a system uplink in the same period of time.10 cl, 8 dwg |
