Title:
MULTIPLE-INPUT MULTIPLE-OUTPUT (MIMO) COMMUNICATION SYSTEM USING A CODEBOOK AND METHOD OF DESIGNING THE CODEBOOK
Document Type and Number:
WIPO Patent Application WO/2011/083945
Kind Code:
A2
Abstract:
Provided is a multiple input multiple output (MIMO) communication system using a codebook. A transmitter and a receiver included in the MIMO communication system may generate a codebook having a different size for each eigenvector of a channel matrix or a channel covariance matrix, based on eigenvalues of the channel matrix or the channel covariance matrix.
