Division of bit streams to produce spatial paths for multicarrier transmission |
摘要 |
The present invention relates to the field of bit-de-/multiplexing in multicarrier MIMO communication systems (e.g. precoded spatial multiplexing MIMO communication systems using adaptive OFDM). The present invention especially relates to a multicarrier MIMO transmitter and a multicarrier MIMO receiver. The multicarrier MIMO transmitter according to the present invention comprises a demultiplexer and symbol mapper 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 transmit ports for respectively transmitting the at least two multicarrier modulated signals, wherein a data throughput rate of each transmission channel is separately variable. |
