Transmit beamforming for wireless multicasting using channel orthogonalization and local refinement
The problem of transmit beamforming for single-group multicasting is considered, where the objective is to transmit common information to a (large) number of users. The transmitte...

The Orientation Adaptive Lapped Orthogonal Transform for Image Coding
In this paper, a lapped orthogonal transform adapted for local directionality of an image is proposed and its application in adaptive image coding is presented. First, we address ...
