ABSTRACT:
An apparatus for transmitting signals with multiple antennas is disclosed. The multiple antenna transmission apparatus performs space-time encoding or space-frequency encoding, and cyclically delays the encoded symbol with a plurality of delay-values to generate a plurality of delayed symbols. The multiple antenna transmission apparatus transmits the plurality of delayed symbols to the channel through a plurality of antennas. By changing the number of space areas for encoding and the number of delay-values for delaying, the number of antennas for the multiple antenna transmission apparatus is easily expanded.
