Modeling the Behavior of Peaks of OFDM Signal Using ‘Peaks Over Threshold’ Approach
Navneet Kumar,Sheetal Kalyani +1 more
TL;DR: New expressions for symbol error probability in the presence of peak-to-average-power-ratio/clipping are derived from the orthogonal frequency division multiplexing systems and are significantly tighter than the expression in the existing literature.
Journal ArticleDOI
SINR Analysis of an IRS Assisted MU-MISO System
TL;DR: This work characterize the outage probability (OP) of an intelligent reflecting surface (IRS) assisted multi-user multiple-input-single-output (MU-MISO) communication system and approximate the signal-to-interference-plus-noise ratio (SINR) for any downlink user by a Log-Normal random variable.
Journal ArticleDOI
Interference Prediction in Partially Loaded Cellular Networks Using Asymmetric Cost Functions
TL;DR: This letter considers interference prediction in a slot using previous interference values and proposes a variant where the weights used for prediction are biased and uses an asymmetric cost function called Linex to observe that these two methods perform significantly better than conventional linear prediction.
Proceedings ArticleDOI
Joint power and resource allocation for D2D communication with low-resolution ADC
TL;DR: A four-step algorithm is proposed that optimizes the ADC resolution profile at the BS to reduce the energy consumption and perform joint power control and resource allocation for D2D users (DUEs) and cellular users (CUEs), and thereby improve the D 2D reliability and maximize CUE rate.
Journal ArticleDOI
On CRB for Parameter Estimation in Two Component Gaussian Mixtures and the Impact of Misspecification
TL;DR: A closed form expression for the Cramer Rao lower bound (CRB) for parameter estimation in the presence of a two component Gaussian mixture noise model is derived and can be lower bounded by a simple two term expression.
