1. A method comprising:

  • receiving, from a base station by a processing system of a channel sounding receiver including at least one processor, at a location, a channel sounding waveform via a plurality of carriers;

    sampling, by the processing system, the channel sounding waveform via the plurality of carriers to generate a plurality of per-carrier time domain sample sets;

    processing, by the processing system, the plurality of per-carrier time domain sample sets via a plurality of discrete fourier transform modules, wherein the processing provides a plurality of per-carrier frequency domain sample sets;

    aligning, by the processing system, the plurality of per-carrier frequency domain sample sets in gain and phase, wherein the aligning provides a combined frequency domain sample set; and

    measuring, by the processing system, a channel property at the location based upon the combined frequency domain sample set.
