Automatic determination of digital modulation types with different noises using convolutional neural network based on time-frequency information
Daldal, Nihat; Cömert, Zafer; Polat, Kemal (Elsevier, 2020)In this study, a novel digital modulation classification model has been proposed for automatically recognizing six different modulation types including amplitude shift keying (ASK), frequency shift keying (FSK), phase-shift ... -
Classification of multi-carrier digital modulation signals using NCM clustering based feature-weighting method
Daldal, Nihat; Polat, Kemal; Guo, Yanhui (Elsevier Science Bv, 2019)This work presents a novel digital modulation signal classification model by combining Neutrosophic c-means (NCM) based feature weighting (NCMBFW) and classifier algorithms. As the digital modulation signal, the multi-carrier ... -
Deep long short-term memory networks-based automatic recognition of six different digital modulation types under varying noise conditions
Daldal, Nihat; Yildirim, Ozal; Polat, Kemal (Springer London Ltd, 2019)In this paper, a new method based on deep learning has been proposed in order to recognize noise-digital modulation signals at varying noise levels automatically. The 8-bit data from six different modulations have been ... -
Estimation of body fat percentage using hybrid machine learning algorithms
Uçar, Muhammed Kürşad; Uçar, Zeliha; Köksal, Fatih; Daldal, Nihat (Elsevier Sci Ltd, 2021)Before obesity treatment, body fat percentage (BFP) should be determined. BFP cannot be measured by weighing. The devices developed to produce solutions to this problem are called "Body Analysis Devices". These devices are ... -

A novel demodulation structure for quadrate modulation signals using the segmentary neural network modelling
Daldal, Nihat; Nour, Majid; Polat, Kemal (Elsevier Sci Ltd, 2020)In digital communication, the baseband information signal is modulated by the high-frequency carrier to produce a passband signal and applied to the transmission line. QASK (quadrature amplitude-shift keying), QFSK (quadrature ... -
A novel demodulation system for base band digital modulation signals based on the deep long short-term memory model
Daldal, Nihat; Şengür, Abdulkadir; Polat, Kemal; Cömert, Zafer (Elsevier Sci Ltd, 2020)For high-frequency digital signals to be transmitted over long distances, the basic digital signal needs to be modulated with a high-frequency carrier. In this case, the baseband digital signal is called the pass-band ... -
Piecewise demodulation based on combined artificial neural network for quadrate frequency shift keying communication signals
Daldal, Nihat; Polat, Kemal (Springer, 2020)The Quadrate Frequency-shift Keying (QFSK) modulation is one of the most widely used modulation methods for transmitting base band signal in the transition band in digital communication. It is a very common modulation type ... -
