Apparatus and method for combining baseband processing and radio frequency beam steering in a wireless communication system

摘要

The present invention , in a wireless communication system , baseband and radio frequency receiver is a combination of multiple signals (RF: Radio Frequency) to provide a method and apparatus for processing . The method includes the steps of receiving information for the channel estimation from the transmitter , based on the information for the channel estimation , the process of confirming the number of routes in the channel , in each of the identified route for one or more signals transmitted from the transmitter , a step of calculating an RF pre- coding matrix for RF precoding with a phase shift (phase shift), baseband precoder associated with the transmitter in , including a process of calculating the baseband precoding matrix to precode the one or more signals .
