Low Complexity Precoding and Detection in Multi-user Massive MIMO OTFS Downlink
Brijesh Chander Pandey, Saif Khan Mohammed, P. Raviteja +2
We consider the problem of degradation in performance of multi-carrier multi-user massive MIMO systems when channel induced Doppler spread is high. Recently, Orthogonal Time Freque…
Polar Coded Repetition for Low-Capacity Channels
Fariba Abbasi, Hessam Mahdavifar, Emanuele Viterbo
Constructing efficient low-rate error-correcting codes with low-complexity encoding and decoding have become increasingly important for applications involving ultra-low-power devic…
OTFS Based Random Access Preamble Transmission For High Mobility Scenarios
Alok Kumar Sinha, Saif Khan Mohammed, P. Raviteja +2
We consider the problem of uplink timing synchronization for Orthogonal Time Frequency Space (OTFS) modulation based systems where information is embedded in the delay-Doppler (DD)…
Index Coding at the WiFi Edge: An Implementation Study for Video Delivery
Lalhruaizela Chhangte, Emanuele Viterbo, D Manjunath +1
HTTP based video streaming has become the de facto standard for video content delivery across different video streaming services. However, video content delivery continues to be ch…
List Viterbi Decoding of PAC Codes
Mohammad Rowshan, Emanuele Viterbo
Polarization-adjusted convolutional (PAC) codes are special concatenated codes in which we employ a one-to-one convolutional transform as a pre-coding step before the polar transfo…
Large Kernel Polar Codes with efficient Window Decoding
Fariba Abbasi, Emanuele Viterbo
In this paper, we modify polar codes constructed with some 2^t x 2^t polarization kernels to reduce the time complexity of the window decoding. This modification is based on the pe…
