Abstract
System and method for subsample time resolution signal alignment. First and second signals may be aligned by iteratively performing the following until a termination condition is met: current samples of the first and second signals may be acquired, a delayed copy of the current samples of the first signal may be generated and subtracted from the current samples of the first signal to generate a third signal, a delayed copy of the current samples of the second signal may be generated with a current subsample delay and subtracted from the current samples of the first signal to generate a fourth signal, and an alignment error may be generated based on the third and fourth signals and the current subsample may be delay adjusted accordingly. The iteratively adjusting may generate a subsample resolution delay aligning the second signal to the first signal. Subsequent samples the first signal and the second signal may be aligned and output per the subsample resolution delay.
