FIELD: information technology.
SUBSTANCE: system comprises means, instructions and operations for combining two signals. In one example, the system comprises at least one baseband modulator, a plurality of amplifiers where signals are multiplied by a gain; one combiner operably connected to the amplifiers, and a phase shifter where one of the signals is phase shifted with respect to the other signal. In another example; the apparatus further comprises a phase shifter operably connected to one baseband modulator to provide a π/2 phase shift between two signals. In another example, at least one baseband modulator comprises a BPSK (binary phase-shift keying) baseband modulator on an I axis and a BPSK baseband modulator on a Q axis.
EFFECT: high downlink quality owing to support of MUROS technology.
