Method for determining a confidence value for an estimated parameter in a wireless positioning system and radio receiver device

A radio receiver device implemented as an anchor point or as a mobile device in a wireless positioning system, the radio receiver device comprising:

• at least one processor;
• and
• at least one storage medium coupled to the at least one processor and storing machine-readable instructions that, when executed by the at least one processor, cause the at least one processor to perform operations comprising:
• receiving a signal comprising a number of signal samples;
• in response to receiving the signal comprising the number of signal samples, pre-processing each sample of the number of signal samples and therefrom providing a number of pre-processed samples;
• calculating a first confidence value for the number of signal samples or for the number of pre-processed samples;
• performing a pre-estimation of a parameter using the number of pre-processed samples and therefrom providing a pre-estimated parameter;
• calculating a second confidence value for the pre-estimated parameter;
• performing a final estimation of the parameter using the pre-estimated parameter and therefrom providing the estimated parameter;
• calculating a third confidence value for the estimated parameter;
• and
• combining at least two of the first confidence value, the second confidence value and the third confidence value and therefrom providing a confidence value for the estimated parameter;
• wherein the confidence value for the estimated parameter is configured to be used in determining a position of the mobile device based on the estimated parameter.

At least one tangible, non-transitory, computer readable storage medium storing instructions that, when executed by one or more processors, cause the one or more processors to perform operations comprising:

• receiving, by at least one anchor point or by at least one mobile device in a wireless positioning system, a signal comprising a number of signal samples;
• in response to receiving the signal comprising the number of signal samples, pre-processing each sample of the number of signal samples and therefrom providing a number of pre-processed samples;
• calculating a first confidence value for the number of signal samples or for the number of pre-processed samples;
• performing a pre-estimation of a parameter using the number of pre-processed samples and therefrom providing a pre-estimated parameter;
• calculating a second confidence value for the pre-estimated parameter,
• performing a final estimation of the parameter using the pre-estimated parameter and therefrom providing the estimated parameter;
• and
• calculating a third confidence value for the estimated parameter,
• combining at least two of the first confidence value, the second confidence value and the third confidence value and therefrom providing the a confidence value for the estimated parameter;
• wherein the confidence value for the estimated parameter is configured to be used in determining a position of the at least one mobile device based on the estimated parameter.
