The invention discloses a multiuser polarization modulation wireless communication transmitter, and aims at providing a wireless communication transmitter capable of containing more users. The multiuser polarization modulation wireless communication transmitter is realized through the technical scheme below: each polarization modulator of N polarization modulators is a single-pole double-throw switch with two input ports C and D and two output ports A and B. The input port D is connected with an output of a local oscillation source while the other input port C receives an input switch control switch si(t); and i=1, ..., N. When a control signal is at a high level, a local oscillation source signal is output from the output port A of each polarization modulator to a combiner 1, and the combiner 1 generates left-handed circular polarization electromagnetic waves; when the control signal is at a low level, the local oscillation source signal is output from the output port B of each polarization modulator to a combiner 2, and the combiner 2 generates right-handed circular polarization electromagnetic waves; two antennas generate two orthogonally polarized electromagnetic waves to cover an antenna work frequency band of all frequency points of the local oscillation source generated signal respectively; and N is the number of users.

The utility model relates to the field of radio frequency simulation systems and discloses a polarization switch module. The polarization switch module comprises a signal channel, a switch matrix and a synthesizer, wherein the signal channel, the switch matrix and the synthesizer are connected in sequence. The signal channel is used for providing a path for input target signals; the switch matrix is used for carrying out polarization selection and combination on the target signals and outputting vertical polarization input signals and horizontal polarization input signals corresponding to an antenna; and the synthesizer is used for classifying, synthesizing and outputting the vertical polarization input signals and the horizontal polarization input signals. The polarization switch module can be used to add radio frequency signals of circular polarization, horizontal polarization and vertical polarization to a radiation unit only capable of generating single polarization and greatly increase transmitting/receiving distance of the antenna.
