Abstract:
1. A method for transmitting data in a multiple-input multiple-output (MIMO) communication system including a transmitter for transmitting a signal via multiple transmission antennas each having unique indexes and at least one receiver for receiving a signal via at least one reception antenna, the method comprising: compressing, at the transmitter, a predetermined number of transmission symbols mapped to each of the transmission antennas into one compressed symbol; inserting space information indicating a transmission antenna, into the compressed symbol; transmitting the compressed symbol via a first transmission antenna from among the multiple transmission antennas; estimating, at the receiver, the compressed symbol from a received signal; estimating, at the receiver, a transmission antenna index corresponding to the first transmission antenna based on phase information of the received signal, wherein the receiver selects a transmission antenna index of which the phase of the received signal is spatially nearest, as the estimated transmission antenna index; and restoring transmission symbols based on the estimated compressed symbol and transmission antenna index.
