SLM based PAPR reduction of OFDM signal using new phase sequence
TL;DR: In this paper, rows of normalised Riemann matrices are selected as phase sequence vectors for the selected mapping (SLM) technique, which is one of the promising PAPR reduction techniques for OFDM.
Proceedings ArticleDOI
A Low Complexity SLM Technique for PAPR Reduction in OFDM Using Riemann Sequence and Thresholding of Power Amplifier
TL;DR: In this article, Riemann sequences are used as a phase vectors along with the thresholding of the power amplifier(PA) to reduce the computational complexity of the selected mapping (SLM) technique.
Proceedings ArticleDOI
Graph Signal Processing of EEG signals for Detection of Epilepsy
TL;DR: Simulation results show that the proposed GDFT based features from Gaussian Weighted Visibility Graph (VG) can detect epileptic seizure with 100 % accuracy.
Proceedings ArticleDOI
Removal of narrowband interference (PLI in ECG signal) using Ramanujan periodic transform (RPT)
TL;DR: This work proposes an approach using Ramanujan periodic transform for reducing PLI and is tested on a subject data from MIT-BIH Arrhythmia database.
Proceedings ArticleDOI
