An Iterative Receiver for OFDM With Sparsity-Based Parametric Channel Estimation.
IEEE Transactions on Signal Processing(2018)
Abstract
In this paper, we design a receiver that iteratively passes soft information between the channel estimation and data decoding stages. The receiver incorporates sparsity-based parametric channel estimation. State-of-the-art sparsity-based iterative receivers simplify the channel estimation problem by restricting the multipath delays to a grid. Our receiver does not impose such a restriction. As a r...
