APPARATUS AND METHOD FOR CHANNEL FEEDBACK IN MULTIPLE INPUT MULTIPLE OUTPUT SYSTEM |
摘要 |
An apparatus and a method for feeding a channel back in a wireless communication system using multiple input multiple output antennas (MIMO) are provided. The method includes receiving a signal from a transmitter and configuring a channel matrix for the received signal, configuring a basis transformed sparse channel using a sparsifying basis function with respect to the channel matrix, selecting a channel part to be fed back to the transmitter from the transformed sparse channel, and creating a codebook by quantizing the selected channel part, and feeding a codebook index corresponding to the created codebook back to the transmitter. |
