Cette lettre présente une technique de réduction de la complexité informatique pour la détection spectrale basée sur la diversité spatiale lorsque le nombre d'antennes de réception est supérieur à trois (NR≥3 où NR est le numéro de l'antenne de réception). Les signaux reçus sont combinés avec une inversion de phase de manière à ne pas atténuer le signal combiné, et une statistique de détection de signal est calculée à partir du signal combiné. Étant donné que le calcul d’une seule statistique est requis quel que soit le nombre d’antennes de réception, la complexité peut être réduite. Des exemples numériques et une analyse simple vérifient l’efficacité de la technique présentée.

Abstract: This letter presents a computational complexity reduction technique for space diversity based spectrum sensing when the number of receive antennas is greater than three (NR≥3 where NR is the number of receive antenna). The received signals are combined with phase inversion so as to not attenuate the combined signal, and a statistic for signal detection is computed from the combined signal. Because the computation of only one statistic is required regardless of the number of receive antenna, the complexity can be reduced. Numerical examples and simple analysis verify the effectiveness of the presented technique.
