Graph Neural Network Based Access Point Selection for Cell-Free Massive MIMO Systems
Vismika Ranasinghe, Nandana Rajatheva, Matti Latva-aho
A graph neural network (GNN) based access point (AP) selection algorithm for cell-free massive multiple-input multiple-output (MIMO) systems is proposed. Two graphs, a homogeneous…

Low Latency Decoder for Short Blocklength Polar Codes
Heshani Gamage, Vismika Ranasinghe, Nandana Rajatheva +1
Polar codes have been gaining a lot of interest due to it being the first coding scheme to provably achieve the symmetric capacity of a binary memoryless channel with an explicit c…

Partially Permuted Multi-Trellis Belief Propagation for Polar Codes
Vismika Ranasinghe, Nandana Rajatheva, Matti Latva-aho
Belief propagation (BP) is an iterative decoding algorithm for polar codes which can be parallelized effectively to achieve higher throughput. However, because of the presence of e…
