RANGING DIVERSITY-RECEPTION METHOD AND RECEIVER
First Claim
1. A method for determining an arrival time of a RF ranging signal at a ranging receiver, comprising:
- receiving at least one RF ranging signal via a plurality of antennas comprised by the ranging receiver;
providing a plurality of antenna signals, each comprising at least a section of the ranging signal as received either by a respective one of the antennas or by a linear combination of at least two of the antennas;
determining respective candidate arrival times of the at least one ranging signal from at least two of the antenna signals;
determining the arrival time of the at least one ranging signal as the earliest candidate arrival time.
