Coded Compressed Sensing with List Recoverable Codes for the Unsourced Random Access
Kirill Andreev, Pavel Rybin, Alexey Frolov
We consider a coded compressed sensing approach for the unsourced random access and replace the outer tree code proposed by Amalladinne et al. with the list recoverable code capabl…
A Polar Code Based TIN-SIC Scheme for the Unsourced Random Access in the Quasi-Static Fading MAC
Kirill Andreev, Evgeny Marshakov, Alexey Frolov
We consider a problem of unsourced random access in the quasi-static Rayleigh fading channel. In the previous work, the authors have proposed LDPC code based solutions based on joi…
Energy efficient coded random access for the wireless uplink
Suhas S Kowshik, Kirill Andreev, Alexey Frolov +1
We discuss the problem of designing channel access architectures for enabling fast, low-latency, grant-free and uncoordinated uplink for densely packed wireless nodes. Specifically…
Design and Decoding of Polar Codes for the Gaussian Multiple Access Channel
Evgeny Marshakov, Gleb Balitskiy, Kirill Andreev +1
Massive machine-type communications (mMTC) is one of the key application scenarios for future 5G networks. Non-orthogonal multiple access (NOMA) is a promising technique for the us…
Achievability Bounds for T-Fold Irregular Repetition Slotted ALOHA Scheme in the Gaussian MAC
Anton Glebov, Nikolay Matveev, Kirill Andreev +2
We address the problem of uncoordinated massive random-access in the Gaussian multiple access channel (MAC). The performance of low-complexity T-fold irregular repetition slotted A…
