Frequency selective transmit signal weighting for multiple antenna communication systems

摘要

According to an aspect of the invention, a method is provided for transmitting a signal over a wireless channel comprising the steps of : acquiring information representative of a state of the channel based upon an initial signal transmitted over the channel; acquiring information representative of a transmission mode of the signal; determining transmit weighting values for the signal as a function of frequency based upon the state of the channel and the transmission mode of the signal; weighting the signal with the transmit weighting values thereby generating a weighted signal; and transmitting the weighted signal in accordance with the transmission mode.
