Decision trees and their variants recently have been proposed. All trees used are fixed M-
ary tree structured, such that the training samples in each node must be artificially divided …

This paper proposes QR-based criteria for efficient selection of multi-mode precoders in
multi-user multiple-input multiple-output (MU-MIMO) precoded systems with a limited …

For a point-to-point multi-input multi-output (MIMO) wireless channel, we propose a
feedback scheme, which consists of transmit-antenna selection algorithm and beamforming …

We consider a signature quantization scheme for a group of users in a reverse-link direct
sequence (DS)-code division multiple access (CDMA). Assuming perfect channel …

This thesis examines various signal processing techniques that are required for establishing
efficient (near optimal) communications in multiuser multiple-input multipleoutput (MIMO) …
