Definitions

  • the present invention relates to a method and device for detection of a signal in a communications system.
  • a method of defecting a first signal in a received signal using a pattern comprising at least one signal group, each signal group comprising a number of signal symbols, the pattern comprising at least one pattern group, each pattern group comprising a number of pattern symbols, wherein the method comprises the steps of: • for each signal group multiplying each signal symbol with a corresponding pattern symbol of a pattern group and deriving a sum of the products of multiplication,
  • the detection threshold is derived based on a signal to interference ratio of a common pilot channel (CPICH).
  • CPICH common pilot channel
  • the detection threshold is derived based on a false detection rate factor and a standard deviation of the interference of the received signal.
  • the signal to interference ratio (SIR) calculated for a common pilot channel (CPICH) is dependent on an estimate of the interference for a given finger and a given group, where said method further comprises the step of:
  • the first signal is an acquisition indicator channel (AICH) signal or a collision detection/channel assignment indicator channel (CD/CA-ICH).
  • AICH acquisition indicator channel
  • CD/CA-ICH collision detection/channel assignment indicator channel
  • the received signal (y) comprises two or three signal groups and the pattern (s) comprises at least two or three pattern groups.
  • the use of two or more groups and thereby two or more weight factors (x) enables a correction of the otherwise destroyed orthogonality and thereby elimination of false and/or unreliable detection at even higher velocities.

Abstract

La présente invention a trait à un procédé (et un dispositif correspondant) de détection d'un premier signal dans un signal reçu au moyen d'une configuration, le signal reçu comportant au moins un groupe de signaux, chaque groupe de signaux comprenant un certain nombre de symboles de signaux, la configuration incluant au moins un groupe de configurations, chaque groupe de configurations incluant au moins un certain nombre de symboles de configuration, le procédé comprenant les étapes suivantes : la multiplication pour chaque groupe de signaux de chaque symbole de signaux avec un symbole de configuration correspondant du groupe de configurations et l'obtention d'une somme de produits de multiplication, l'application d'un facteur de pondération parmi un ou plusieurs facteurs de pondération à chaque somme produisant une somme pondérée, où ledit un ou lesdits plusieurs facteurs de pondération sont choisis de manière à préserver une relation d'orthogonalité desdits symboles de configuration dudit au moins un groupe de configurations, et la détermination pour savoir si un signal est détecté ou non en fonction de ladite une somme ou desdites plusieurs sommes pondérée(s).
