Sparse Channel Estimation for OFDM-Based Underwater Acoustic Systems in Rician Fading With a New OMP-MAP Algorithm
Panayırcı, Erdal; Altabbaa, Mhd Tahssin; Uysal, Murat; Poor, H. Vincent (IEEE, 2019)In this paper a new channel estimation algorithm is proposed that exploits channel sparsity in the time domain for an orthogonal frequency division multiplexing (OFDM)-based underwater acoustical (UWA) communications systems ... -
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 ... -
Subchannel Allocation and Power Control for Uplink Femtocell Radio Networks with Imperfect Channel State Information
Altabbaa, Mhd Tahssin; Arsan, Taner; Panayırcı, Erdal (Springer, 2019)Femtocell technology is emerging as a key solution for mobile operators for its advantage in coverage and capacity enhancement along with its cost effectiveness. However, densely and randomly deployed femtocells while ...
