Title:
APPARATUS AND METHOD FOR GENERATING CODEBOOK IN A WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2011/118962
Kind Code:
A3
Abstract:
An apparatus and method for generating a codebook in a wireless communication system are disclosed. The codebook generation apparatus includes a processor for generating a covariance matrix of a channel between the transmitting end and a receiving end, using a unitary matrix including a first vector corresponding to at least one quantized dominant singular vector of the channel and a second vector corresponding to at least one basis vector of a null space of the first vector, and transforming a predefined first codebook by applying the covariance matrix of the channel to the first codebook.
