Frequency selective transmit signal weighting for multiple antenna communication systems

摘要

A method for communication includes performing by one or more processors and/or circuits in a communication device functions including determining transmit power weights, which are to be utilized for communicating one or more wireless signals via a wireless channel, as a function of frequency of a wireless signal communicated via the wireless channel. The determining may be based on a transmission mode of the wireless signal and a state of the wireless communication channel. Transmit antenna spatial weights may be determined for communicating the one or more wireless signals via a plurality of antennas. The one or more wireless signals may be weighted with the transmit power weights and/or one of the transmit antenna spatial weights. The weighted one or more wireless signals may be transmitted via one of a plurality of antennas in accordance with the transmission mode.
