Efficient spectral access in distributed cooperative cognitive radio networks
(Institute of Electrical and Electronics Engineers Inc., 2021)
The cognitive users (CUs) in the cooperative communication may serve as relay nodes for conveying the signal received from the primary users (PUs) to their destinations, provided that both the PUs and the CUs minimum rate ...
Sparse coding with enhanced atom selection for FDD massive MIMO channel estimation
(Institute of Electrical and Electronics Engineers Inc., 2021)
In sparse coding-based channel estimation, atom selection is based on jointly minimizing the sparsity and the error of the representation of the noisy measurement. However, this selection is not necessarily optimal in terms ...
Validity and reliability of the Turkish version of screening tool on distress in fertility treatment (SCREENIVF)
(NLM (Medline), 2021)
BACKGROUND: Women diagnosed with infertility and receiving infertility treatment reported high levels of depressive symptoms, anxiety and distress. Infertile women should first be screened for psychosocial risks. Psychosocial ...

Estimation and exploitation of multidimensional sparsity for MIMO-OFDM channel estimation
(Institute of Electrical and Electronics Engineers Inc., 2022)
Obtaining accurate channel state estimates at reasonable training overheads remains a big challenge for the applicability of multiple-input multiple-output orthogonal frequency division multiplexing (MIMO-OFDM). Recently, ...
Deep RL-based spectrum occupancy prediction exploiting time and frequency correlations
(Institute of Electrical and Electronics Engineers Inc., 2022)
In cognitive radio systems, predicting spectrum occupancies is a convenient alternative way to continuous spectrum sensing. It can provide information on spectrum usage and so empty spectrum bands can be used by secondary ...
Index modulation-aided IQ imbalance compensator for OTFS communications systems
(Institute of Electrical and Electronics Engineers Inc., 2022)
Design of simple transceiver architectures is inevitable in order to provide low computational complexity, low power consumption and affordable cost in beyond 5G (B5G) wireless systems, but it results in hardware impairments ...
Orthogonal coexistence of overlapped radar and communication waveforms
(Institute of Electrical and Electronics Engineers Inc., 2022)
With revolutionary new services and applications, integrated sensing and communication has been essential for recent and future wireless communication systems. For the communication systems, the cyclic prefix - orthogonal ...
