COMBINING BASEBAND PROCESSING AND RADIO FREQUENCY BEAM STEERING IN WIRELESS COMMUNICATION SYSTEMS |
摘要 |
A method and apparatus enable combined baseband (BB) and radio frequency (RF) processing of signals. The method includes receiving, by a receiver, channel estimation information for a channel between a transmitter and the receiver. The method includes identifying a plurality of paths in the channel based on the channel estimation information. 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 BB precoding matrix for precoding the one or more signals by a BB precoding unit associated with the transmitter.
