GpsMultiCorrelator is a MATLAB class includes the properties and methods necessary for:
  • The setting of a local signal in terms of hypotheses on received signal (PRN, Doppler and code phase),
  • The definition of correlator characteristics, in terms of filter frequencies, correlator code phases, integration period and code phase increment to be applied at the end of integration period,
  • The injection of a received signal, as complex temporal values (see GpsSignals class for the synthesis of GPS signals),
  • The calculation of energy matrices, for the defined filter frequencies and correlator code phases and non-coherent integration period, taking into account the code phase increment updating the next matrix correlator code phases,
  • The calculation of in-phase/quadrature components, for the defined correlator code phases and a coherent integration period of 1ms,
  • The estimation of through non-coherent and coherent methods, applied to in-phase/quadrature components,
  • The estimation of code phase through a discriminator based on early, prompt and late correlators, applied to in-phase/quadrature components.
