A commonly considered image manipulation is to conceal undesirable objects or people in the scene with a region of pixels copied from the same image. Forensic mechanisms aimed at ...
While an exact stationarization of a process with a given spectrum magnitude can be obtained via a complete randomization of the spectrum phase (“surrogates” technique), we pr...
This paper deals with the localization of multiple sources from two-channel mixtures recorded in a reverberant environment. We introduce new angular spectrum-based methods relying...
When the arrival timing difference exists in the uplink MUMIMO systems, the conventional MUD techniques, without timing control, failed under this circumstance. In this paper, we ...
1 A relay station (RS)-based cellular system deployment is considered, where multiple base stations (BS) cooperate in the BSRS in-band transmission for the downlink. With the joint...
