Sparse underwater acoustic channel estimation in colored Gaussian noise [Renkli? Gauss gürültülü seyrek sualtı akusti?k kanalların kestirimi]
(IEEE, 2012)
Cooperative underwater acoustic communication systems come into prominence in recent years. Since underwater channels are sparse and additive noise entering the system is colored Gaussian noise. Therefore it is very difficult ...
Space time turbo coded OFDM system with transmit and receive antenna selection
(IEEE, 2011)
In this paper a space-time turbo coded (STTC) orthogonal frequency division multiplexing (OFDM) system with QPSK signalling is explored when joint transmit and receive antenna selection is employed. Maximization of signal ...
Realization of ideal filter characteristics via genetic algorithm
(2011)
In this paper realization of ideal filter characteristics via genetic algorithm has been studied. The filter is defined as a lossless two-port terminated normalized source and load resistances and the coefficients of its ...
Thyroid and breast cancer disease diagnosis using Fuzzy-neural networks
(2009)
In this paper a new hybrid structure in which Neural Network and Fuzzy Logic are combined is proposed and its algorithm is developed. Fuzzy-CSFNN Fuzzy-MLP and Fuzzy-RBF structures are constituted and their performances ...
Transfer matrix factorization based synthesis of resistively terminated LC ladder networks
(2009)
In this paper a transfer matrix factorization based synthesis algorithm for resistively terminated low-pass LC ladder networks is presented. In the algorithm component value of the extracted element and the reflection ...
A new approach for coexistence of IEEE 802.11af and IEEE 802.22 systems
(Institute of Electrical and Electronics Engineers Inc., 2018)
In this paper various algorithms are proposed to help IEEE 802.11af and IEEE 802.22 wireless systems to coexist in TV white space by considering multiple techniques. By using busy tone power control and multihop communication ...
Routing performance analysis of opportunistic networks with flooding and partial flooding methods [Fırsatçı a?larda taşırma ve kısmi taşırma yöntemleriyle yönlendirme performans analizi]
(IEEE, 2012)
Opportunistic networks is one of the fast developing research areas in mobile communications. Under opportunistic networks mobile nodes try to communicate with other nodes without any prior information and knowledge about ...
Empirical results about efforts for effective teaching to y-generation freshman students
(IEEE, 2012)
New techniques are deployed to teach the new generation of students effectively. This work tries to share our experience in a blended course for over eleven years. It has been observed that the online portion of the course ...
The effect of secondary user locations on the cooperative detection performance [İki?nci?l kullanıcı konumlarının i?şbi?rli?kli? algılama yöntemi? performansına etki?si?]
(IEEE, 2012)
In conventional cooperative detection a fusion center decides on the presence or absence of the primary user by gathering all the information from secondary users and conveys this decision to all users. This approach does ...
Genetic algorithm based broadband equalizer design with ripple level control
(IEEE, 2012)
In this paper broadband equalizer design with ripple control via genetic algorithm has been studied. The equalizer is defined as a lossless two-port terminated by load impedance and the coefficients of its describing ...
