TRANSMISSION DEVICE AND TRANSMISSION METHOD Russian patent published in 2020 - IPC H04B7/413 

FIELD: electrical communication engineering.

SUBSTANCE: invention relates to communication engineering and can be used in wireless communication systems. For this purpose, there are provided M signal processors, which accordingly generate modulated signals for M receiving devices (where M is an integer greater than or equal to 2), a multiplexing signal processor and N antenna sections (where N is an integer greater than or equal to 1). In the case of transmitting multiple streams, each of the M signal processors generates two mapped signals, generates first and second pre-encoded signals by pre-encoding two displayed signals, periodically changes phase of signal points in IQ plane relative to second pre-encoded signal, outputs a phase-modified signal and outputs the first pre-encoded signal and the phase-modified signal as two modulated signals. In case of single stream transmission, each of M signal processors outputs single modulated signal. Multiplexing signal processor multiplexes the modulated signals output from M signal processors and generates N multiplexed signals. N antenna sections, respectively, transmit N multiplexed signals.

EFFECT: technical result consists in improved bandwidth.
