Abstract
A disclosed computer-implemented method may include (1) receiving a channel estimation signal comprising a plurality of frequency domain signals, each frequency domain signal corresponding to an antenna in a plurality of antennas, a port in a plurality of ports, and a demodulation reference signal sequence, (2) for each frequency domain signal, (A) converting the frequency domain signal to a time domain signal, and (B) determining a power level of the time domain signal, (3) determining, for each port in the plurality of ports (a) a sum of the power levels of the time domain signals corresponding to the port, each antenna in the plurality of antennas, and the DMRS sequence, and (b) based on the determined sum corresponding to the port, measuring (i) a pre-equalization signal-to-interference-plus noise ratio, and (ii) a power delay profile (PDP). Various other systems and methods are also disclosed.
