ON THE GAUSSIAN PROCESS FOR STATIONARY AND NON-STATIONARY TIME SERIES PREDICTION FOR THE QATAR STOCK MARKET
(2024 , Master Thesis)This research adopts a Gaussian prediction model for non-stationary time series. Then, we discuss four transformation techniques: Generalized Optimal Wavelet Decomposition Algorithm (GOWDA), Hilbert Huang transform (HHT), ... -
On the group proportional fairness of frequency domain resource allocation in L-SC-FDMA based LTE uplink
( IEEE , 2010 , Conference Paper)Localized single carrier frequency division multiple access (L-SC-FDMA) has been selected as the uplink transmission scheme in 3GPP Long Term Evolution (LTE) due to its low Peak to Average Power Ratio (PAPR) over OFDMA in ... -
On the Higher Order Statistics of the Channel Capacity in Dispersed Spectrum Cognitive Radio Systems Over Generalized Fading Channels
( Institute of Electrical and Electronics Engineers Inc. , 2016 , Article)This work is devoted to the study of dispersed spectrum cognitive radio (CR) systems over independent and nonidentically distributed (i.n.i.d.) generalized fading channels. More specifically, this is performed in terms of ... -
On the increasing importance of multiple criteria decision aid methods for portfolio selection
( Taylor and Francis Ltd. , 2018 , Article)In 1952, Markowitz published his famous paper on portfolio selection that transformed the field of finance. Although over 65years have passed since then, the mean-variance model remains today the predominant model in ... -
On the Investigation of Monthly River Flow Generation Complexity Using the Applicability of Machine Learning Models
( Hindawi Limited , 2021 , Article)Streamflow is associated with several sources on nonstationaries and hence developing machine learning (ML) models is always the motive to provide a reliable methodology to understand the actual mechanism of streamflow. ... -
On the joint scheduling and intra-cell interference coordination in multi-relay LTE uplink
