One of the critical challenges in multicarrier-based systems is peak to average power ratio (PAPR). Recently, Filter Bank Multicarrier (FBMC) proved be a promising candidate that can replace traditional orthogonal multiplexing division (OFDM) scheme due its better spectral efficiency, reducing both inter-channel interference (ICI) and PAPR. Due their advantages PAPR without impacting BER, Hadam...

background: about half of all patients who undergo mitral valve surgery suffer from atrial fibrillation (af). cox described the surgical cut-and-sew maze procedure, which is an effective surgical method but has some complications. this study was designed to evaluate the efficacy of a substitution method of radiofrequency ablation (rfa) for patients undergoing mitral valve surgery with af. metho...
