1. A method, comprising:
receiving, by a processing device, a first indication that a first estimated error value does not satisfy a first predetermined threshold value, the first estimated error value related to (i) a first number of signal paths and (ii) a first estimated characteristic of a radio frequency (RF) signal observed by an antenna array;
computing, by the processing device, responsive to receiving the first indication that the first estimated error value does not satisfy the first predetermined threshold value, a second estimated error value related to (i) a second number of signal paths larger than the first number of signal paths and (ii) a second estimated characteristic of the RF signal;
receiving, by the processing device, a second indication that the second estimated error value satisfies a second predetermined threshold value; and
outputting, by the processing device, the second estimated characteristic of the RF signal.
