METHOD AND APPARATUS FOR TRANSMITTING BITSTREAM IN A MULTIPLE INPUT MULTIPLE OUTPUT SYSTEM

摘要

Disclosed are a method and an apparatus for transmitting a bit stream in a multiple-input multiple-output system. The apparatus for transmitting a bit stream in a multiple-input multiple-output system according to the present invention comprises: a coding and modulation unit for coding and modulating each of a plurality of packets obtained by packetizing a bit stream; a space-time coding unit for performing optimal space-time coding on the packets according to a simulation result of each of the packets modulated by the coding and modulation unit by using a combination of at least two among a first space-time coding method, a second space-time coding method, and a third space-time coding method; and a transmission unit for transmitting the space-time coded packets. The apparatus of the present invention can transmit the bit stream at high speed by selecting the optimal space-time coding method.
