This paper proposes an idea of developing a model of estimating timing offset error of OFDM (Orthogonal Frequency Division Multiplexing) system without the use of additional pilots relying on inherent characteristics of the OFDM signal. An analytical expression has been derived and formulated to analyze the effect of bit error rate (BER) due to timing(More)
MANET(mobile ad-hoc networks) is a type of network in which mobile nodes communicate to each other via radio waves. MANET is self configuring, infrastructure-less and robust network that's why nowadays its routing protocols become active research area. In this paper , literature survey of on-demand AODV and DSR routing protocols is to be discussed with(More)
Cognitive radio (CR) is an upcoming technology that provides viable solution for congested wireless spectrum. The basic idea behind cognitive radio is the utilization of unused frequency bands of primary or licensed users (PU) by secondary or unlicensed users (SU). The unused licensed spectrum is called white space or spectrum hole. CR utilizes these(More)
