Biography

Md. Sharif Hossen is working as a Lecturer in the Department of Information and Communication Technology (ICT) at Comilla University (CoU), Bangladesh. He was formerly Lecturer in Department of Computer Science and Engineering (CSE) at Southeast University (SEU), and research assistant in Department of Information and Communication Engineering (ICE) at University of Rajshahi (RU). He completed his B. Sc. (Bachelor of Science) and M. Sc. (Master of Science) from Dept. of ICE at University of Rajshahi, Bangladesh. He achieved faculty first position in both degrees. His research interests include delay-tolerant networking, wireless ad hoc, sensor, underwater and vehicular networks, as well as considerations of privacy in the Internet of Things. He is also interested in applying big data techniques. He has seven international journal papers (viz. Scopus Index, Springer), thirteen international conference papers (viz. IEEE, Springer) and one book chapter (viz. Taylor and Francis). He received several scholarships like ICT research fellowship (for M. Sc. thesis), UGC scholarship (for B. Sc.), and Merit scholarship for outstanding academic result at University of Rajshahi. He received Best Paper Award at IEEE ICISET 2016 conference at IIUC, Bangladesh and at Springer ICACIE 2018 conference at SOA University, India. He is the reviewer of several international journals (viz. Wireless Personal Communications, Springer).

PAPR Reduction in OFDM System Using Clipping and Filtering Methods Based on CCDF

Wireless communication systems are becoming so promising day-by-day due to the mobility and the dynamicity of communication pattern. But, to fulfill the wide range of user’s demand it has become much important to use some techniques which would be most efficient in terms of bandwidth and speed. The multicarrier strategy, called as orthogonal frequency division multiplexing (OFDM) has outstanding features to fulfill these demands. Multipath fading, delay spread, frequency selective fading and inter channel interference all of these limitations of wireless communication compound it with the scarcity of bandwidth gave rise to OFDM. However, the high peak-to-average power ratio is a great problem or a barrier in OFDM which causes the signal being distorted with the insufficient power at the receiver. There are some specified techniques to minimize it. In this paper, we have used clipping and filtering methods to minimize the effect of peak-to-average power ratio.
