Ergodic Capacity and Optimal Handover in Satellite Mega-Constellations under Finite Serving Times
Brendon McBain, Yi Hong, Emanuele Viterbo
Existing analyses of ergodic capacity in satellite mega-constellations often rely on restrictive serving time assumptions or become intractable under realistic handover strategies.…
OTFS Channel Estimation and Detection for Channels with Very Large Delay Spread
Preety Priya, Yi Hong, Emanuele Viterbo
In low latency applications and in general, for overspread channels, channel delay spread is a large percentage of the transmission frame duration. In this paper, we consider OTFS…
Deterministic Pilot Design and Channel Estimation for Downlink Massive MIMO-OTFS Systems in Presence of the Fractional Doppler
Ding Shi, Wenjin Wang, Li You +4
Although the combination of the orthogonal time frequency space (OTFS) modulation and the massive multiple-input multiple-output (MIMO) technology can make communication systems pe…
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…
