Journal ArticleDOI
Performance Analysis of OFDM-Based Nonlinear AF Multiple-Relay Systems
TL;DR: A novel closed-form expression of average symbol error rate for a general order rectangular quadrature amplitude modulation scheme is investigated by using the well-known cumulative distribution function-based approach.
Journal ArticleDOI
Hyperparameter-Free Transmit-Nonlinearity Mitigation Using a Kernel-Width Sampling Technique
TL;DR: In this paper, the authors propose a methodology of assigning kernel-bandwidths that capitalizes on a stochastic sampling of kernel-widths using an ensemble drawn from a pre-designed probability density function.
Journal ArticleDOI
Adaptive multiple stage K-best successive interference cancellation algorithm for MIMO detection
TL;DR: The proposed adaptive multiple stage K-best successive interference cancellation algorithm for symbol vector detection in multiple-input multiple-output systems performs better than the MMSE and the SIC based detection schemes, and achieves a near ML performance.
Journal ArticleDOI
Performance analysis of AF OFDM system using multiple relay in presence of nonlinear-PA over inid Nakagami-m fading
TL;DR: Performance of an orthogonal frequency division multiplexing–based variable-gain amplify and forward cooperative system using multiple relay with relay selection is analyzed over independent but not necessarily identically distributed frequency selective Nakagami-m fading channels.
Proceedings ArticleDOI
User Fairness and Performance Enhancement for Cell Edge User in NOMA-HCN with Offloading
TL;DR: Analysis of the gain of non-orthogonal multiple access (NOMA), an enabling technique for 5G, in a heterogeneous cellular network, finds that offloading to FBS tier with NOMA gives better performance as compared to offloading without NomA.
