Patent ID: 7515649

Claim:
A method of transmitting a signal using multiple antennas, comprising: allocating bit-mapped symbols to the multiple antennas based on a correlation among the multiple antennas, wherein a pair of symbols farthest in distance to each other are allocated to a pair of antennas having a high correlation and a pair of symbols closest in distance to each other are allocated to a pair of antennas having a low correlation, wherein the bit-mapped symbols are allocated to the multiple antennas according to a detection efficiency of each symbol in addition to the correlation among the multiple antennas, and wherein allocating the bit-mapped symbols allocates bit-mapped symbols transmitted from antennas having a higher correlation among each other to be retransmitted from antennas having a lower correlation among each other, and allocates bit-mapped symbols transmitted from antennas having a lower correlation among each other to be retransmitted from antennas having a higher correlation among each other.
