Channel Estimation Based on Machine Learning Paradigm for Spatial Modulation OFDM
Ahmed M. Badi, Taissir Y. Elganimi, Osama A. S. Alkishriwo +1
In this paper, deep neural network (DNN) is integrated with spatial modulation-orthogonal frequency division multiplexing (SM-OFDM) technique for end-to-end data detection over Ray…
Instantaneous frequency estimation using the discrete linear chirp transform and the Wigner distribution
Osama A. Alkishriwo, Luis F. Chaparro
In this paper, we propose a new method to estimate instantaneous frequency using a combined approach based on the discrete linear chirp transform (DLCT) and the Wigner distribution…
Combined Image Encryption and Steganography Algorithm in the Spatial Domain
Aya H. S. Abdelgader, Raneem A. Aboughalia, Osama A. S. Alkishriwo
In recent years, steganography has emerged as one of the main research areas in information security. Least significant bit (LSB) steganography is one of the fundamental and conven…
A Novel Chaotic Uniform Quantizer for Speech Coding
Osama A. S. Alkishriwo
Quantization is an essential step in the analog-to-digital conversion process and it is very important in all modern telecommunication systems. In this paper, a novel chaotic unifo…
Iterative Time-Varying Filter Algorithm Based on Discrete Linear Chirp Transform
Osama A. S. Alkishriwo, Ali A. Elghariani, Aydin Akan
Denoising of broadband non--stationary signals is a challenging problem in communication systems. In this paper, we introduce a time-varying filter algorithm based on the discrete…
Color Image Encryption Based on Chaotic Block Permutation and XOR Operation
Raneem A. Aboughalia, Osama A. S. Alkishriwo
In this paper, chaotic block image permutation and XOR operation are performed to achieve image encryption. The studied method of encryption makes use of chaotic systems properties…
