Code design for MIMO downlink with imperfect CSIT
—In this letter, we implement a simplified version of the Cover - van der Meulen - Hajek - Pursley (CMHP) coding originally characterized by Wajcer, Wiesel, and Shamai. The vect...

Registration Techniques for Using Imperfect and Partially Calibrated Devices in Planar Multi-Projector Displays
Abstract-- Multi-projector displays today are automatically registered, both geometrically and photometrically, using cameras. Existing registration techniques assume pre-calibrate...

Dirty-Paper Coding without Channel Information at the Transmitter and Imperfect Estimation at the Receiver
—In this paper, we examine the effects of imperfect channel estimation at the receiver and no channel knowledge at the transmitter on the capacity of the fading Costa’s channel...

Closed-Loop Transmit Diversity with Imperfect Feedback
The closed-loop transmit diversity technique is used to improve the performance of the downlink channel in MIMO communication systems. In these closed-loop systems, feedback delay...

Improved iterative detection and achieved throughputs of OFDM systems under imperfect channel estimation
Abstract--Assuming imperfect channel estimation, we propose an improved detector for orthogonal frequency-division multiplexing (OFDM) systems over a frequency-selective fading cha...
