Channel Estimation and Equalization for Alamouti SF-Coded OFDM-UWA Communications
Panayırcı, Erdal; Altabbaa, Mhd Tahssin; Poor, H-Vincent (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2021-02)In this paper, a new channel estimation and equalization algorithm for underwater acoustic (UWA) communications is presented. The proposed algorithm is developed to meet the requirements of underwater time-varying sparse ... -
Fuzzy logic for decision extraction from product reviews
Altabbaa, Mhd Tahssin; Ayabakan, Tarik; Öğrenci, Arif Selçuk (Institute of Electrical and Electronics Engineers Inc., 2018)Most of manufacturers and merchants sell their products via internet websites where customers buy them and write their reviews regarding the purchased product. These reviews carry a lot of information. Prospective customers ... -
Power Control and Resource Allocation in TDD-OFDM Based Femtocell Networks with Interference
Altabbaa, Mhd Tahssin; Arsan, Taner; Panayırcı, Erdal (IEEE, 2017)Femtocell technology is a promising solution for different dilemmas in cellular networks. In femtocell power control the interference experienced by the network is divided into two main tiers according to the type of network ... -
Sparse channel estimation and data detection algorithms for ofdm-based underwater acoustic communication systems
Altabbaa, Mhd Tahssin (Kadir Has Üniversitesi, 2018)Communication over acoustic signals in underwater results into a multi-scale multilag channels which occurs due to the multipath propagation. Hence a robust channel estimation technique has to be present at the receiver ... -
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 ...
