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…
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)…
Decoding of NB-LDPC codes over Subfields
V. B. Wijekoon, Emanuele Viterbo, Yi Hong
The non-binary low-density parity-check (NB-LDPC) codes can offer promising performance advantages but suffer from high decoding complexity. To tackle this challenge, in this paper…
