Title (EN) METHOD AND SYSTEM FOR CONCURRENT ESTIMATION OF FREQUENCY OFFSET AND MODULATION INDEX
(FR) PROCEDE ET SYSTEME D'ESTIMATION SIMULTANEE DU DECALAGE DE FREQUENCE ET DE L'INDICE DE MODULATION
Abstract: front page image
(EN)A system for estimating the modulation index and frequency offset of a CPM signal. An estimator filters the received signal and utilizes a training sequence to determine the modulation index and frequency offset of the CPM signal. The estimator can also include a post-processing step to eliminate all or part of a bias that might be created by the estimator.
(FR)L'invention concerne un système d'estimation de l'indice de modulation et du décalage de fréquence d'un signal CPM. Un estimateur filtre le signal reçu et utilise une séquence d'apprentissage pour déterminer l'indice de modulation ainsi que le décalage de fréquence du signal CPM. L'estimateur peut également soumettre le signal à un post-traitement pour éliminer tout ou partie d'un biais dont il peut être à l'origine.
