FIELD: information technologies.
SUBSTANCE: systems and methods are described, which promote transmission and reception of signals along I and Q branches of a communication channel to suppress the potential T/Q imbalance. The device may transmit a signal along I and Q branches to distribute capacity of transmission substantially evenly for this channel. The device demodulates data with the help of a code or a matrix comprising actual and complex modifiers, creating as a result the signal of I and Q branch for transmission. If the channel comprises multiple resources, the device may alternate or implement transmission along the I branch in one resource and the Q branch in the other resource for this signal, in order to distribute capacity. Besides, the device may apply the code of complex scrambling to distribute the signal along I and Q branches. The device may also use QPSK or modulation of a higher order, to send signals intended for one and the same user.
EFFECT: increased throughput capacity of a communication channel by transmission of data along I and Q branches in order to reduce noise and I and Q imbalance of signal transmission capacity.
