Machine Learning-Based Channel State Estimators for 5G Wireless Communication Systems.

Publication Type: Academic Journal

Source(s): CMES-Computer Modeling in Engineering & Sciences. 2023, Vol. 135 Issue 1, p755-778. 24p.

Abstract: For a 5G wireless communication system, a convolutional deep neural network (CNN) is employed to synthesize a robust channel state estimator (CSE). The proposed CSE extracts channel information from transmit-and-receive pairs through offline training t...

Optimization of Channel Estimation Using ELMx-based in Massive MIMO.

Publication Type: Academic Journal

Source(s): Computers, Materials & Continua. 2022, Vol. 73 Issue 1, p103-118. 16p.

Abstract: In communication channel estimation, the Least Square (LS) technique has long been a widely accepted and commonly used principle. This is because the simple calculation method is compared with other channel estimation methods. The Minimum Mean Squares ...

Investigation of Vehicular S-LSTM NOMA Over Time Selective Nakagami-m Fading with Imperfect CSI.

Publication Type: Academic Journal

Source(s): Journal of Telecommunications & Information Technology. 2022, Issue 4, p47-59. 13p.

Abstract: In this paper, the performance of a deep learningbased multiple-input multiple-output (MIMO) non-orthogonal multiple access (NOMA) system is investigated for 5G radio communication networks. We consider independent and identically distributed (i.i.d.) ...

A Nonconventional Auxiliary Information Based Robust Class of Exponential-type Difference Estimators.

Publication Type: Academic Journal

Source(s): Mathematical Problems in Engineering. 9/19/2022, p1-13. 13p.

Abstract: This study proposes a new class of improved exponential-type difference estimators of finite population mean by using supplementary information of known median along with suitable combinations of the conventional and non-conventional measures of the au...

A novel improved class of ratio-product type exponential estimators of population variance.

Publication Type: Academic Journal

Source(s): Scientia Iranica. Transaction E, Industrial Engineering. Jul/Aug2022, Vol. 29 Issue 4, p2115-2133. 19p.

Abstract: Several auxiliary information-based estimators of population variance are available in the existing literature on survey sampling. Mostly, these estimators are based on conventional dispersion measures of the auxiliary variable. In this study, a genera...

Analysis of an LSTM-based NOMA Detector Over Time Selective Nakagami-m Fading Channel Conditions.

Publication Type: Academic Journal

Source(s): Journal of Telecommunications & Information Technology. 2022, Issue 3, p14-24. 8p.

Abstract: This work examines the efficacy of deep learning (DL) based non-orthogonal multiple access (NOMA) receivers in vehicular communications (VC). Analytical formulations for the outage probability (OP), symbol error rate (SER), and ergodic sum rate for the...

Generalized variance estimator using auxiliary information in the presence and absence of measurement error.

Publication Type: Academic Journal

Source(s): Scientia Iranica. Transaction B, Mechanical Engineering. Jul/Aug2022, Vol. 29 Issue 4, p1868-1879. 12p.

Abstract: This study proposes a new generalized estimator based on auxiliary information for the estimation of population variance in the presence and absence of measurement error. Approximate expressions of bias and mean square error of the proposed generalized...

Adjustment Method of "FAST" Active Reflector Based on Optimal Fitting Strategy.

Authors:

Abstract: The adjustment method of the fast active reflector of "Chinese heavenly eye" is studied. Firstly, this paper studies the offset characteristics of fast main cable node position, combined with the position of the celestial body to be measured, the follo...

A New Generalized Class of Exponential Factor-Type Estimators for Population Distribution Function Using Two Auxiliary Variables.

Publication Type: Academic Journal

Source(s): Mathematical Problems in Engineering. 8/8/2022, p1-13. 13p.

Abstract: In this article, we propose a generalized class of exponential factor type estimators for estimation of the finite population distribution function (PDF) using an auxiliary variable in the form of the mean and rank of the auxiliary variable exist. The ...
