AIM Due to surgery s high mortality and morbidity, local therapeutic techniques are required for Barrett s high-grade dysplasia (BHGD) and early gastric cancer (EGC). Various techniques are available for endoscopic mucosal resection (EMR) in the GI tract. The " suck and cut technique, which uses a transparent cap or modified multiband variceal ligator, is usually the most practiced method. A mu...

This paper presents the advantage of using a new modulation scheme called dual carrier Modulation (DCM) compared to classical Quadrature Phase Shift Keying (QPSK) modulation. This comparison is done at data transmission broadband in Multiband OFDM system (MBOFDM) based on Ultra Wide Band UWB. Simulation results show that the use of the modulation DCM for high data rates is more efficient compar...
