摘要： Methods and apparatus for transmitting data via multiple antennas by using antenna diversity. A transmission diversity scheme is established such that two transmission matrices that are in accordance with the space frequency block code combined with Frequency switched transmit diversity (SFBC+FSTD) scheme, are alternatively applied in either the frequency domain, or the time domain, or both of the frequency domain or then time domain. The symbols in the transmission matrices may be transmitted either as one burst in a primary broadcast channel (PBCH), or as discrete bursts in the primary broadcast channel.
