An Approximate Maximum Likelihood Time Synchronization Algorithm for Zero-padded OFDM in Channels with Impulsive Gaussian Noise
Koosha Pourtahmasi Roshandeh, Mostafa Mohammadkarimi, Masoud Ardakani
In wireless communication systems, Orthogonal Frequency-Division Multiplexing (OFDM) includes variants using either a cyclic prefix (CP) or a zero padding (ZP) as the guard interva…
Decision Directed Channel Estimation Based on Deep Neural Network k-step Predictor for MIMO Communications in 5G
Mehrtash Mehrabi, Mostafa Mohammadkarimi, Masoud Ardakani +1
We consider the use of deep neural network (DNN) to develop a decision-directed (DD)-channel estimation (CE) algorithm for multiple-input multiple-output (MIMO)-space-time block co…
Signature-based Non-orthogonal Multiple Access (S-NOMA) for Massive Machine-Type Communications in 5G
Mostafa Mohammadkarimi, Muhammad Ahmad Raza, Octavia A. Dobre
The problem of providing massive connectivity in Internet-of-Things (IoT) with a limited number of available resources motivates the non-orthogonal multiple access (NOMA) solutions…
Doppler Spread Estimation in MIMO Frequency-selective Fading Channels
Mostafa Mohammadkarimi, Ebrahim Karami, Octavia A. Dobre +1
One of the main challenges in high-speed mobile communications is the presence of large Doppler spreads. Thus, accurate estimation of maximum Doppler spread (MDS) plays an importan…
