ABSTRACT:
In an apparatus and method for providing transmit (Tx) diversity in a multi-antenna wireless communication system, Tx diversity is provided by estimating a channel to each antenna using a signal received from the antenna, estimating channel state information (CSI) from the first Tx node to each antenna using the estimated channel, and determining a signal to be transmitted to the antennas in different methods according to whether phase compensation is required for information to be transmitted using the estimated channel and the CSI.
