End-to-end Learning of Probabilistic and Geometric Constellation Shaping with Iterative Receivers
Harindu Jayarathne, Dileepa Marasinghe, Nandana Rajatheva +1
An end-to-end learning method for constellation shaping with a shaping-encoder assisted transceiver architecture is presented. The shaping encoder, which produces shaping bits with…
Machine Learning-Based Channel Prediction for RIS-assisted MIMO Systems With Channel Aging
Nipuni Ginige, Arthur Sousa de Sena, Nurul Huda Mahmood +2
Reconfigurable intelligent surfaces (RISs) have emerged as a promising technology to enhance the performance of sixth-generation (6G) and beyond communication systems. The passive…
Constellation Shaping under Phase Noise Impairment for Sub-THz Communications
Dileepa Marasinghe, Le Hang Nguyen, Jafar Mohammadi +3
The large untapped spectrum in the sub-THz allows for ultra-high throughput communication to realize many seemingly impossible applications in 6G. One of the challenges in radio co…
Automatic and Flexible Transmission of Semantic Map Images using Polar Codes for End-to-End Semantic-based Communication Systems
Hossein Rezaei, Thushan Sivalingam, Nandana Rajatheva
Semantic communication represents a promising roadmap toward achieving end-to-end communication with reduced communication overhead and an enhanced user experience. The integration…
An Alternating Algorithm for Uplink Max-Min SINR in Cell-Free Massive MIMO with Local-MMSE Receiver
W. A. Chamalee Wickrama Arachchi, K. B. Shashika Manosha, N. Rajatheva +1
The problem of max-min signal-to-interference plus noise ratio (SINR) for uplink transmission of cell-free massive multiple-input multiple-output (MIMO) system is considered. We as…
Contextual Bandit Learning for Machine Type Communications in the Null Space of Multi-Antenna Systems
Samad Ali, Hossein Asgharimoghaddam, Nandana Rajatheva +2
In this paper, a novel approach based on the concept of opportunistic spatial orthogonalization (OSO) is proposed for interference management between machine type communications (M…
A Directed Information Learning Framework for Event-Driven M2M Traffic Prediction
Samad Ali, Walid Saad, Nandana Rajatheva
Burst of transmissions stemming from event-driven traffic in machine type communication (MTC) can lead to congestion of random access resources, packet collisions, and long delays.…
Multi-Operator Spectrum Sharing for Small Cell Networks : A Matching Game Perspective
Tachporn Sanguanpuak, Sudarshan Guruacharya, Nandana Rajatheva +2
One of the many problems faced by current cellular network technology is the under utilization of the dedicated, licensed spectrum of network operators. An emerging paradigm to sol…
