description A disclosed computer-implemented method may include receiving, as part of a demodulation reference signal (DMRS) channel estimation operation, a frequency domain channel estimation signal comprising a plurality of DMRS samples, and generating an extended channel estimation signal by: (A) determining an extended DMRS sample that extends at least one edge of the channel estimation signal based on: (i) an edge DMRS sample included in the plurality of DMRS samples at the edge of the channel estimation signal, and (ii) at least one additional DMRS sample included in the plurality of DMRS samples, and (B) extending the edge of the channel estimation signal by including the DMRS samples and the extended DMRS sample in the extended channel estimation signal. The method may also include generating an augmented channel estimation signal by extrapolating a frequency edge for the augmented channel estimation signal. Various other systems and methods are also disclosed.
