Une classe d'algorithmes multimodules (MMA(p)) optimisés par une taille de pas (OS) optimale pour l'égalisation aveugle sont d'abord étudiés dans cette lettre. Le critère multimodule (MM) est essentiellement une fonction de coût partagé qui implémente séparément la partie réelle et imaginaire du signal, la phase peut donc être récupérée conjointement avec l'égalisation. Plus important encore, la taille de pas menant au minimum du critère MM le long de la direction de recherche peut être obtenue algébriquement parmi les racines d'un polynôme d'ordre supérieur à chaque itération, ce qui donne un algorithme multimodule de taille de pas optimal robuste (OS-MMA(p)) est développé. Les résultats expérimentaux démontrent des performances améliorées de l'algorithme proposé pour atténuer l'interférence inter-symboles (ISI) par rapport à l'algorithme de module constant OS (OS-CMA). En outre, la complexité informatique peut être réduite grâce à l’algorithme OS-MMA(2) proposé.

Abstract: A class of multimodulus algorithms (MMA(p)) optimized by an optimal step-size (OS) for blind equalization are firstly investigated in this letter. The multimodulus (MM) criterion is essentially a split cost function that separately implements the real and imaginary part of the signal, hence the phase can be recovered jointly with equalization. More importantly, the step-size leading to the minimum of the MM criterion along the search direction can be obtained algebraically among the roots of a higher-order polynomial at each iteration, thus a robust optimal step-size multimodulus algorithm (OS-MMA(p)) is developed. Experimental results demonstrate improved performance of the proposed algorithm in mitigating the inter-symbol interference (ISI) compared with the OS constant modulus algorithm (OS-CMA). Besides, the computational complexity can be reduced by the proposed OS-MMA(2) algorithm.
