Mitigation of Error Propagation in Decision Directed OFDM Channel Tracking Using
TL;DR: In this article, decision-directed channel tracking (DDCT) is treated as an outlier contaminated Gaussian regression problem, where the source of outliers are the incorrect symbol decisions.
Proceedings ArticleDOI
Interference Mitigation in Turbo-Coded OFDM Systems Using Robust LLRs
TL;DR: The proposed LLR computation method exploits the fact that NBI/CCI has a CG probability density function but does not assume knowledge of the NBI power, NBI pdf and the fraction of subcarriers affected by NBI.

Outage Probability Expressions for an IRS-Assisted System with and without Source-Destination Link for the Case of Quantized Phase Shifts
TL;DR: This work derives three simple approximations for the outage probability of an intelligent reflecting surface (IRS) assisted communication system in a fading environment and demonstrates how the method of moment matching and KL divergence minimization can be used to analyze systems experiencing spatial correlation between the IRS elements.
Journal ArticleDOI
Coverage Probability and Achievable Rate Analysis of FFR-Aided Multi-User OFDM-Based MIMO and SIMO Systems
TL;DR: The impact of frequency domain correlation amongst the OFDM sub-bands allocated to the FR1 and FR3 cell-regions is analysed and it is shown that the presence of correlation reduces both the coverage probability and the average throughput of the FFR network.

Sarath Gopi,Sheetal Kalyani +1 more
TL;DR: In this article, a peak-to-average power ratio (PAPR) efficient non-coherent orthogonal frequency division multiplexing with index modulation (OFDM-IM) was proposed.
