Title:
APPARATUS AND METHOD FOR COMBINING BASEBAND PROCESSING AND RADIO FREQUENCY BEAM STEERING IN A WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2013/015664
Kind Code:
A2
Abstract:
A method and apparatus enable combined baseband (BB) and radio frequency (RF) processing of signals. The method includes receiving, by a receiver, information for estimating a channel between a transmitter and the receiver. The method includes identifying a plurality of paths in the channel based on the information for channel estimation. The method includes calculating an RF precoding matrix for precoding one or more signals to be transmitted on each of the identified paths. The RF precoding matrix includes a phase shift for each of the identified paths. Additionally, the method includes calculating a baseband precoding matrix for precoding the one or more signals by a baseband precoder associated with the transmitter.
