Abstract:
A method of measuring transmission of a transmitter within a communication system, the method comprising the steps of:collecting a first set of one or more signal features of a first transmitter signal received at a first receiver wherein said first set of signal features comprises a data content of said first transmitter signal;forwarding said first set of signal features to a second receiver;creating a replica of said first transmitter signal at said second receiver in response to said first set of signal features;correlating said replica with a second transmitter signal received at said second receiver; anddetermining a second set of one or more signal features for said second transmitter signal as received at said second receiver;determining a first location parameter of said first transmitter signal in response to said first set of signal features;determining a second location parameter of said second transmitter signal in response to said second set of signal features; andestimating a position of said transmitter in response to said first and second location parameters.
