摘要:
Generally, this disclosure provides systems and methods for distributed phased array multiple input multiple output (DPA-MIMO) communications. A system may comprise a baseband processing unit; a plurality of beamforming (BF) modules each of which comprises at least a beamforming antenna and a transceiver circuit comprising at least a downconverter that downconverts a beamformed antenna radio frequency signal to an intermediate frequency signal, and an upconverter that upconverts an intermediate frequency signal to radio frequency and sends to said beamforming antenna for transmission; a plurality of intermediate frequency (IF) radios, each of which comprises a receive chain circuit that includes at least a downconverter that downconverts an intermediate frequency signal sent from said BF module to a basedband signal conveyed to said baseband processing unit, and a transmit chain circuit that includes at least an upconverter that upconverts a baseband signal received from said baseband processing unit to an intermediate frequency signal which is conveyed to said beamforming module; and a plurality of cables or any type of physical signal transmission medium, each of which connects one of said beamforming modules with one of said intermediate frequency radios.
