An Iterative Receiver for OFDM With Sparsity-Based Parametric Channel Estimation
Thomas L. Hansen, Peter B. Jørgensen, Mihai-Alin Badiu +1
In this work we design a receiver that iteratively passes soft information between the channel estimation and data decoding stages. The receiver incorporates sparsity-based paramet…
