Patent ID: 8005031

Claim:
A method for transmitting a signal in a wireless communication system comprising a transmitter with at least four transmit antennas and a receiver with at least one receive antenna, the method comprising: a) performing Space Frequency Block Coding (SFBC) processes for blocks to be transmitted through each of two antenna pairs and outputting signal blocks on which SFBC has been performed whose number corresponds to the number of transmit antennas; and b) performing a Space Time Block Coding (STBC) process for the signal blocks generated according to the antenna pairs, consecutively, and transmitting signals carried by single carriers through the at least four transmit antennas mapped to the signal blocks, wherein step a) comprises: performing an SFBC process for signals to be transmitted through first and third antennas and outputting first signal blocks mapped to the first and third antennas; and performing an SFBC process for signals to be transmitted through second and fourth antennas and outputting second signal blocks mapped to the second and fourth antennas.
