Joint channel and carrier frequency estimation for M-ary CPM over frequency-selective channel using PAM decomposition

Romain Chayot, Marie-Laure Boucheret, Charly Poulliat, Nathalie Thomas, Nicolas Van Wambeke, Guy Lesthievent

ICASSP 2017accepted

In this paper, we present a new data-aided carrier-recovery method for Continuous Phase Modulation (CPM) signals over frequency-selective channels. We first present a linear model of the received signal based on Mengali representation over selective channels and show how to use it to perform joint c…

Multisymbol with memory noncoherent detection of CPFSK

Charles-Ugo Piat-Durozoi, Charly Poulliat, Marie-Laure Boucheret, Nathalie Thomas, Emmanuel Bouisson, Guy Lesthievent

ICASSP 2017accepted

Multisymbol receiver is an effective method to demodulate noncoherent sequences. However it is necessary to correlate an important number of symbols in a noncoherent scheme to reach the performances carried out by optimal coherent Maximum a Posteriori (MAP) detectors such as BCJR. In this paper, we…

Blind estimation of unknown time delay in periodic non-uniform sampling: Application to desynchronized time interleaved-ADCs

Jean-Adrien Vernhes, Marie Chabert, Bernard Lacaze, Guy Lesthievent, Roland Baudin, Marie-Laure Boucheret

ICASSP 2016accepted

Increasing the sampling rate of Analog-to-Digital Converters (ADC) is a main challenge in many fields and especially in telecommunications. Time-Interleaved ADCs (TI-ADC) were introduced as a technical solution to reach high sampling rates by time interleaving and multiplexing several low-rate ADCs…
