Transmission apparatus and method for MIMO system

摘要

A transmitter in a multiple input multiple output (MIMO) communication system is provided. The transmitter includes a multiplexer for multiplexing an input bit stream into symbols, and outputting the symbols in parallel; a bit/symbol mapper for reordering bits constituting the symbols, which are output from the multiplexer in the same time period, and outputting the reordered bits as mapped symbols; and a modulator for modulating the parallel mapped symbols output from the bit/symbol mapper according to their associated modulation schemes, and transmitting the modulated symbols via their associated antennas.
