Low-PAPR Joint Channel Estimation and Data Detection in ZP-OTFS System
Omid Abbassi Aghda, Mohammad Javad Omidi, Hamid Saeedi-Sourck
Orthogonal Time Frequency Space (OTFS) systems face significant challenges in channel estimation due to high pilot overhead and peak-to-average power ratio (PAPR). To address these…
Superimposed Channel Estimation in OTFS Modulation Using Compressive Sensing
Omid Abbassi Aghda, Mohammad Javad Omidi, Hamid Saeedi-Sourck
Orthogonal time frequency space (OTFS) technique is a two-dimensional modulation method that multiplexes information symbols in the delay-Doppler (DD) domain. OTFS combats high Dop…
Power Allocation for a HAPS-Enabled MIMO-NOMA System with Spatially Correlated Channels
Rozita Shafie, Mohammad Javad Omidi, Omid Abbasi +1
High-altitude platform station (HAPS) systems are considered to have great promise in the multi-tier architecture of the sixth generation (6G) and beyond wireless networks. A HAPS…
Low-Complexity Resource Allocation for Dense Cellular Vehicle-to-Everything (C-V2X) Communications
Mohammad Hossein Bahonar, Mohammad Javad Omidi, Halim Yanikomeroglu
Vehicular communications are the key enabler of traffic reduction and road safety improvement referred to as cellular vehicle-to-everything (C-V2X) communications. Considering the…
Distributed pricing-based resource allocation for dense device-to-device communications in beyond 5G networks
Mohammad Hossein Bahonar, Mohammad Javad Omidi
Considering the dramatic increase of data rate demand in beyond fifth generation (5G) networks due to the numerous transmitting nodes, dense device-to-device (D2D) communications w…
Centralized QoS-Aware Resource Allocation for D2D Communications with Multiple D2D Pairs in One Resource Block
Mohammad Hossein Bahonar, Mohammad Javad Omidi
Device-to-device (D2D) communications can result in spectral efficiency (SE) improvement of cellular networks when interference is addressed properly. For further improvement of ov…
Energy Efficient Precoder in Multi-User MIMO Systems with Imperfect Channel State Information
Hossein Vaezy, Mohammad Javad Omidi, Halim Yanikomeroglu
This article is on the energy efficient precoder design in multi-user multiple-input-multiple-output (MU-MIMO) systems which is also robust with respect to the imperfect channel st…
