Sparse Channel Estimation for Space-Time Block Coded OFDM-Based Underwater Acoustic Channels
Altabbaa, Mhd Tahssin; Öğrenci, Arif Selçuk; Panayırcı, Erdal; Poor, H. Vincent (Institute of Electrical and Electronics Engineers Inc., 2018)Communication over acoustic signals underwater results in multi-scale multi-lag channels due to multipath propagation. Hence a robust channel estimation technique has to be present at the receiver. In this paper assuming ... -
