Detection of spectrum holes in Cognitive Radio Networks (CRNs) is possible using theory of compressive sensing (CS). At the same time, these unlicensed Cognitive secondary users (SUs) must reliably detect the presence of licensed users or owners of spectrum holes to avoid interference. Precise localization of the transmitting nodes is a complicated but(More)
With the advancement in technology, the number of electronic devices in our day-to-day lives has increased to make life simpler. So a necessity to construct a Universal Remote System that will easily control all these devices from a distance will not only reduce the complexity of handling the number of devices simultaneously, but also save power. This paper(More)
We investigate the effects of antenna parameters on the radiation characteristics of a compact size Rectangular Microstrip Antenna suitable for mobile application. In the calculations of antenna parameters, resonant frequency is set at 3 GHz. In our investigations three low cost substrate materials, namely: (a) irradiated poly-guide with relative dielectric(More)
We investigate the Coulomb breakup of neutron rich nuclei 11Be and 19,17,15C within a theory developed in the framework of Distorted Wave Born Approximation. Finite range effects are included by a local momentum approximation, which allows incorporation of realistic wave functions for these nuclei in our calculations. Energy and angular as well as parallel(More)
The mobile radios, whether they are part of a cellular system or an Ad Hoc wireless network of sensors, are meant to support extreme forms of portability – cell to cell in the same cluster, cluster to cluster, city to city, country to country and in the case of Ad Hoc networks, one route to another. Consequently, the frequency of the radio receiver has to(More)
We have modeled and simulate asymmetric microstrip folded dipole antenna on substrate materials and study the antenna performances. The conventional wire dipole antenna configurations are converted into corresponding microstrip version. The complementary nature of parallel coplanar strip line and waveguide models have been used to model the dipole antenna.(More)
We calculate the Coulomb dissociation of 9Li on Pb and U targets at 28.5 MeV/A beam energy within a finite range distorted wave Born approximation formalism of the breakup reactions. Invoking the principle of detailed balance, these cross sections are used to determine the excitation function and subsequently the rate of the radiative capture reaction(More)
The popularity of radio communication is increasing day by day but the availability of free radio spectrum is proving to be more difficult. Paradoxically a sizable part of total radio frequency spectrum is either underutilized or not utilized at all. To overcome this situation, Cognitive Radios or radios with built in automatic sensing facility have been(More)
Three parasitic gut worms, one cestode and two acanthocephalan species, have been recorded from two fresh water live fishes (Channa punctatus and Channa striatus) of Channidae family from West Bengal, India for the first time. These parasites were revealed from new host species which were hitherto not reported till now. The cestode is Bothriocephalus(More)
