A New Filter-Bank Multicarrier System With Two Prototype Filters for QAM Symbols Transmission and Reception
TL;DR: It is shown that the proposed FBMC-QAM system satisfies the suggested orthogonality conditions and can use the multiple-input multiple-output transmission schemes as the conventional orthogonal frequency division multiplexing (OFDM) systems.
Proceedings ArticleDOI
A new filter-bank multicarrier system for QAM signal transmission and reception
TL;DR: Numerical results showed that the proposedFBMC-QAM system has almost the same bit error rate (BER) performance compared to the FBMC-OQAM and the orthogonal frequency division multiplexing (OFDM) system.
Proceedings ArticleDOI
Synchronization Error in QAM-Based FBMC System
TL;DR: Numerical results show that FBMCQAM is more robust against CFO while it is more sensitive to TO compared to the FBMC-OQAM system.
Journal ArticleDOI
Simplified Power Allocation Scheme for Cognitive Multi-Node Relay Networks
TL;DR: The proposed PA method with much lower complexity performs close to the suboptimal PA method using interior point method and the closed-form solution of the simplified optimization problem is obtained.
Proceedings ArticleDOI
Low Complexity Multiple Relay Selection Scheme for Cognitive Relay Networks
TL;DR: Power allocation (PA) and multiple relay selection (MRS) for cognitive relay networks (CRNs) are considered and the proposed suboptimal MRS scheme with much lower complexity performs close to the optimal MRS using the exhaustive search.
