Time of arrival estimation

A receiver device comprising:

• one or more antennas for receiving a signal from a transmitter device;
• and
• a data processing system including at least one processor configured to:
• correlate the signal as transmitted by the transmitter device and the signal as received by the receiver device with each other, wherein the transmitter device is a base station of a mobile communication system, wherein the signal comprises in its frequency spectrum:
• a first signal component spanning a first frequency range,
• a second signal component spanning a second frequency range, and
• a third signal component spanning a third frequency range, wherein
• the first frequency range and second frequency range are separated by an intermediate frequency range that does not contain a signal component of the signal,
• the second frequency range and third frequency range are separated by a second intermediate frequency range that does not contain a signal component of the signal;
• wherein a lowest frequency present in the signal and a highest frequency present in the signal are separated by a frequency range of at least 250 MHz wide;
• and
• determine the signal's time of arrival at the receiver device based on the performed correlation.

A non-transitory computer-readable medium comprising a computer program, the computer program comprising instructions which, when the program is executed by a receiver device comprising at least one processor, cause the at least one processor to:

• correlate a signal as transmitted by a transmitter device and the signal as received by the receiver device with each other, wherein the transmitter device is a base station of a mobile communication system, wherein the signal comprises in its frequency spectrum:
• a first signal component spanning a first frequency range,
• a second signal component spanning a second frequency range, and
• a third signal component spanning a third frequency range, wherein
• the first frequency range and second frequency range are separated by an intermediate frequency range that does not contain a signal component of the signal,
• the second frequency range and third frequency range are separated by a second intermediate frequency range that does not contain a signal component of the signal,
• wherein a lowest frequency present in the signal and a highest frequency present in the signal are separated by a frequency range of at least 250 MHz wide;
• and
• determine the signal's time of arrival at the receiver device based on the performed correlation.
