Classification: CPC B | IPC B

Claim 8:
9. A system for estimating one or more actual electrical parameters of a track circuit, comprising:
a transmitter of the track circuit;
a receiver of the track circuit;
a track section of the track circuit which is interposed between said transmitter and said receiver and is suitable to transmit signals output by said transmitter to said receiver; and
a controller,
wherein said transmitter is configured to transmit over said track section towards said receiver at least one signal comprising at least one data packet part, and
wherein said controller is configured to:
decode the at least one signal received at said receiver to determine the at least one data packet part received;
simulate one or more signals by varying an actual value input for one or more parameters of a set of electrical parameters of the track circuit, each simulated signal corresponding to an actual set of values input for the set of electrical parameters;
compare each simulated signal generated with the at least one signal received at said receiver until finding at least a part of a simulated signal that substantially matches a corresponding part of the signal received at said receiver; and
estimate as the actual electrical parameters of said track circuit the actual set of values of the electrical parameters corresponding to the simulated signal that matches the at least one signal received at said receiver.
