International audience; The latest standardization DVB-S2X increases the achievable spectral efficiency of the satellite communications by around 15% in AWGN channel. In order to benefit from those improvements, the strong non-linear distortions intr

International audience; Faster-than-Nyquist (FTN) signaling appears as an attractive method to improve spectral efficiency at the price of an increased complexity at the receiver. The receiver generally implements a turbo-equalization/detection schem

In this paper, we present an interleaver design method for SCCC. Our design criterion is to minimize the message-round probability in the SCCC graph which is specially well suited for SCCC. The message-round probability characterizes the message flow

Edge detection in speckled SAR images using the continuous wavelet transform

Autor: Jean-Yves Tourneret, Marie Chabert, G. Mesnager

Publikováno v: IGARSS '96. 1996 International Geoscience and Remote Sensing Symposium.

This study presents an original method to detect edges in synthetic aperture radar images corrupted by speckle. The authors show that the continuous wavelet transform (CWT) allows to accurately detect edges embedded in speckle. Edges give rise to a c

Phase detection involving parity-check equations and suited to transmissions at low signal to noise ratio

Autor: A. Ducasse, G. Mesnager, Marie-Laure Boucheret, M. Dervin

Publikováno v: ICC

We introduce in this paper a carrier phase detector suited to transmissions at very low signal to noise ratio. Based on the soft decoding of parity check equations, the synchronization scheme proposed here for a QPSK modulation outperforms a classica
