Asynchronous Cell-Free Wireless Networks
Hossein Maleki, Angel Lozano, Hamid Jafarkhani
This paper introduces intentional symbol-level asynchronicity as an interference-management mechanism for the uplink of cell-free networks. Rather than treating timing offsets as i…
Channel-Estimation-Free Beamforming for RIS-Assisted Systems with Limited Feedback
Hossein Maleki, Hamid Jafarkhani
In this article, we consider received-power maximization in RIS-assisted wireless links using only limited received signal strength (RSS) feedback, avoiding explicit estimation of…
Dual-Function Radar-Communication Beamforming with Outage Probability Metric
Hossein Maleki, Carles Diaz-Vilor, Ali Pezeshki +2
The integrated design of communication and sensing may offer a potential solution to address spectrum congestion. In this work, we develop a beamforming method for a dual-function…
Modulation and Coding for NOMA and RSMA
Hamid Jafarkhani, Hossein Maleki, Mojtaba Vaezi
Next-generation multiple access (NGMA) serves as an umbrella term for transmission schemes distinct from conventional orthogonal methods. A key candidate of NGMA, non-orthogonal mu…
