The invention relates to a threshold extension block phase estimator (TEBPE) which gives improved performance over existing BPE algorithms in the presence of noise. Specifically, the threshold and sector slip performance is superior to that of previously disclosed algorithms. This can be of crucial advantage in coded systems. Another attribute of the TEBPE is that it can be configured as a hybrid feedback loop incorporating characteristics of both the BPE and the PLL. This gives a high degree of flexibility with very fast acquisition times at high signal-to-noise ratio (SNR), and improved threshold performance at low SNR.

L'invention concerne un estimateur de phase de bloc à seuil amélioré (TEBPE) permettant d'obtenir une performance améliorée par rapport aux algorithmes d'estimateur de phase de bloc (BPE) en présence de bruit. Plus exactement, l'efficacité du glissement en seuil et secteur est supérieure à celle des algorithmes traditionnels, ce qui peut constituer un avantage non négligeable dans des systèmes chiffrés. Ce TEBPE présente en outre l'avantage de pouvoir être configuré sous la forme d'une boucle de contre-réaction hybride, présentant les mêmes caractéristiques qu'un BPE et qu'un circuit asservi en phase. On obtient ainsi une plus grande flexibilité et des temps d'acquisition très rapides pour un rapport signal-bruit (SNR) élevé, ainsi qu'un seuil amélioré pour un SNR faible.
