Claim Text:
1. A computer-implemented method, comprising: receiving data characterizing a first signal and a second signal; calculating, based on the received data, a first stream of bits for the first signal and a second stream of bits for the second signal, wherein each bit in the first stream of bits characterizes a slope of a power of the first signal and each bit in the second stream of bits characterizes a slope of a power of the second signal; comparing bitwise the first stream of bits and the second stream of bits at a plurality of time-alignment differences for matching bits; and determining, based on the comparing, a final time-alignment difference between the first signal and the second signal; determining, at each of the plurality of time-alignment differences, a sum of matching bits; wherein the determining the final time-alignment difference includes at least one of the following: wherein at least one of the receiving, the calculating, the comparing, the determining the final time-alignment difference, the determining the sum of matching bits is performed by at least one processor of at least one computing system.
