Abstract
The methods and apparatus disclosed herein processes reference signals in an antenna diversity system, e.g., where both the transmitting and receiving devices use multiple antennas. The solution presented herein process reference signals at the transmitting device in such a way to enable the receiving device to efficiently and accurately estimate the covariance matrix associated with data transmitted using transmitter diversity. This is achieved by processing the reference signals used for the covariance estimation and the data signals in the same way, e.g., by precoding data and reference signal portions of one or more signals using the same coding scheme.
