Abstract
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, generating an extended channel estimation signal by determining at least one extended DMRS sample that extends at least one edge of the channel estimation signal, and generating an augmented channel estimation signal by extrapolating, based on the extended channel estimation signal, a frequency edge for the augmented channel estimation signal. The method may also include designing, based on a measurement of a DMRS value included in the augmented channel estimation signal, a polyphase filter, and estimating a DMRS channel by filtering the augmented channel estimation signal using the designed polyphase filter. Various other systems and methods are also disclosed.
