Sparse coding for transform domain-based sparse OFDM channel estimation
(IEEE-Inst Electrical Electronics Engineering Inc, 2019)
In orthogonal frequency division multiplexing (OFDM) systems, frequency domain pilot-aided channel estimation is based on interpolating a down-sampled version of the channel frequency response. This is achieved by transforming ...
