Linear precoder design through cut-off rate maximization in MIMO-OFDM coded systems with imperfect CSIT
This paper proposes a linear transmitter design that aims at minimizing the packet error rate (PER) using partial channel state information at the transmitter (CSIT). The design is...

Optimality of beamforming for MIMO multiple access channels via virtual representation
In this paper, we consider the optimality of beamforming for achieving the ergodic capacity of multiple-input multiple-output (MIMO) multiple access channel (MAC) via virtual repre...

The design and evaluation of interleaved authentication for filtering false reports in multipath routing WSNs
In this paper, we consider filtering false reports in braided multipath routing sensor networks. While multipath routing provides better resilience to various faults in sensor net...

RepFinder: Finding Approximately Repeated Scene Elements for Image Editing
Repeated elements are ubiquitous and abundant in both manmade and natural scenes. Editing such images while preserving the repetitions and their relations is nontrivial due to over...
