TRANSMISSION METHOD FOR MIMO SYSTEM

摘要

A signal transmission method for a multiple input multiple output (MIMO) communication system. A transmitter having a plurality of transmission antennas receives antenna selection information from a receiver having at least one reception antenna. The transmitter selects at least two transmission antennas based on the antenna selection information, beamforms space-time block coding (STBC)-coded input signals with a weighting matrix, and transmits the beamformed signals via the selected transmission antennas. The antenna selection information is generated based on exact channel characteristics and statistical channel characteristics for the transmission antennas and a spatial correlation between the transmission antennas.
