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.
  • the invention also relates to a device for detecting a first signal in a received signal using a. pattern, the received signal 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 at least a number of pattern symbols, wherein the device comprises:
  • AICH detection is used throughout this specification, the invention may also be used for detecting other types of signals with similar properties.
  • a signal is the Collision Detection/Channel Assignment Indicator Channel (CD/CA-ICH) according to the 3rd generation partnership project (3GPP) specifications.
  • CD/CA-ICH was also previously denoted CD-ICH.
  • Figure 1 illustrates a schematic block diagram of a general embodiment of a detection circuit according to the present invention
  • the weight factors are derived from the signal to interference ratio (SIR), calculated for the CPICH.
  • SIR signal to interference ratio
  • ⁇ /SR is a predefined parameter e.g. set to 1/16.
  • ISRf"f H here ISRf"f H
  • the acquisition indicator is given by the above mentioned expression.
  • ⁇ ⁇ estimates the standard deviation of the interference of the signal given by the above-mentioned first result.
  • FAR probability for false detections
  • the weight factor may be pre-determined or derived as described elsewhere.
  • Figure 5 illustrates a number of AICH signature patterns according to 3GGP TS 25.211 V4.3.0 (2201-12).
