FIELD: radio engineering, communication.
SUBSTANCE: present invention relates to bit-demultiplexing/multiplexing in multicarrier MIMO communication systems. The present invention particularly relates to a multicarrier MIMO transmitter and a multicarrier MIMO receiver. The multicarrier MIMO transmitter according to the present invention comprises a demultiplexing and symbol mapping unit for receiving an input bit stream and generating a plurality of symbol streams, each symbol stream being associated with a different transmission channel and comprising a plurality of data symbols, each data symbol being attributed to a different carrier; one or more multicarrier modulators for generating at least two multicarrier modulated signals based on the symbol streams; and at least two transmission ports for respectively transmitting the at least two multicarrier modulated signals, wherein the data throughput rate of each transmission channel is separately variable.
EFFECT: improved communication quality.
