Probabilistic Amplitude Shaping and Nonlinearity Tolerance: Analysis and Sequence Selection Method
Mohammad Taha Askari, Lutz Lampe, Jeebak Mitra
Probabilistic amplitude shaping (PAS) is a practical means to achieve a shaping gain in optical fiber communication. However, PAS and shaping in general also affect the signal-depe…
Comparison of Short Blocklength Sphere Shaping and Nonlinearity Compensation in WDM Systems
Abdelkerim Amari, Lutz Lampe, O. S. Sunish Kumar +2
In optical communication systems, short blocklength probabilistic enumerative sphere shaping (ESS) provides both linear shaping gain and nonlinear tolerance. In this work, we inves…
Full Characterization of Optimal Uncoded Placement for the Structured Clique Cover Delivery of Nonuniform Demands
Seyed Ali Saberali, Lutz Lampe, Ian Blake
We investigate the problem of coded caching for nonuniform demands when the structured clique cover algorithm proposed by Maddah-Ali and Niesen for decentralized caching is used fo…
Decentralized Coded Caching Without File Splitting
Seyed Ali Saberali, Lutz Lampe, Ian Blake
Coded caching is an effective technique to reduce the redundant traffic in wireless networks. The existing coded caching schemes require the splitting of files into a possibly larg…
Adaptive Delivery in Caching Networks
Seyed Ali Saberali, Hamidreza Ebrahimzadeh Saffar, Lutz Lampe +1
The problem of content delivery in caching networks is investigated for scenarios where multiple users request identical files. Redundant user demands are likely when the file popu…
Hardware Impairments Aware Transceiver Design for Bidirectional Full-Duplex MIMO OFDM Systems
Omid Taghizadeh, Vimal Radhakrishnan, Ali Cagatay Cirik +2
In this paper we address the linear precoding and decoding design problem for a bidirectional orthogonal frequencydivision multiplexing (OFDM) communication system, between two mul…
