An Iterative Receiver for OFDM With Sparsity-Based Parametric Channel Estimation [PDF]
, 2018 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 parametric channel estimation.

Optimization Algorithm for DOA Estimation of a Shallow Sea Target Based on Active Time Reversal [PDF]
Xibei Gongye Daxue Xuebao, 2018 Time reversal technique is applied to the DOA estimation of a shallow sea target, and a method based on active time reversal (ATR) is proposed to achieve correct estimation under multipath and low signal-to-noise (SNR) conditions. Combining the classical

Estimation of Sparse MIMO Channels with Common Support [PDF]
, 2011 We consider the problem of estimating sparse communication channels in the MIMO context. In small to medium bandwidth communications, as in the current standards for OFDM and CDMA communication systems (with bandwidth up to 20 MHz), such channels are ...
