Dans un système DS/SS (Direct-Sequence/Spread-Spectrum), un récepteur RAKE est utilisé pour améliorer les performances d'un taux d'erreur binaire (BER). Le récepteur RAKE peut collecter plus d'énergie de signal via des chemins indépendants et atteindre une diversité de chemins. Le récepteur RAKE obtient un gain de diversité supplémentaire grâce à un échantillonnage fractionné. Cependant, la consommation d'énergie du récepteur RAKE augmente proportionnellement à la fréquence d'échantillonnage et ne maximise pas toujours le rapport signal sur bruit (SNR). Par conséquent, des schémas de sélection du taux d'échantillonnage ont été proposés pour réduire le taux d'échantillonnage moyen sans dégrader le BER. Ces schémas sélectionnent les positions des prises et le taux d'échantillonnage en fonction des conditions du canal et la consommation d'énergie peut être réduite. Dans cet article, les schémas de sélection du taux d'échantillonnage pour le système DS/SS sont étudiés à travers une expérience puisqu'il n'y a pas eu de résultats numériques grâce à une expérience. Les résultats numériques montrent que la consommation d'énergie peut être réduite même grâce à l'expérience sans dégradation du BER.

Abstract: In a Direct-Sequence/Spread-Spectrum (DS/SS) system, a RAKE receiver is used to improve a bit error rate (BER) performance. The RAKE receiver can collect more signal energy through independent paths and achieve path diversity. The RAKE receiver obtains further diversity gain through fractional sampling. However, the power consumption of the RAKE receiver increases in proportion to a sampling rate and does not always maximize the signal-to-noise ratio (SNR). Therefore, sampling rate selection schemes have been proposed to reduce the average sampling rate without degrading the BER. These schemes select the tap positions and the sampling rate depending on channel conditions and the power consumption can be reduced. In this paper, sampling rate selection schemes for the DS/SS system are investigated through an experiment since there have been no numerical results through an experiment. Numerical results show that the power consumption can be reduced even through the experiment without the degradation of the BER.
