In this paper, joint co-operative spectrum sensing and data transmission in Amplify and Forward (AF) relay assisted network is observed. The problem is mathematically formulated as maximization of secondary energy efficiency (EE) under the constraints of both sensing performance and interference threshold to primary users (PU). Extensive simulation results(More)
Today, we have required to accommodate a large number of users under a single base station. This can be possible only if we have some flexibility over the spectrum. Previously we have lots of multiplexing methods to accommodate large number of signals in time and frequency domain. But now we have required to accommodate a large number of users in the same(More)
In this work, a cooperative scenario of cognitive network is considered to maximize the energy efficiency and throughput while maintaining certain boundary conditions like, probability of detection threshold and total power budget allocation. After evaluation of the mathematical form, simulation is done on the basis of relay amplifying factor. Additionally,(More)
In the present situation, the expectation about the quality of signals in wireless communication is as high as possible. This quality issue is dependent upon the different communication parameters. One of the most important issues is to reduce the bit error rate (BER) to enhance the performance of the system. This paper provides a comparative analysis on(More)
MIMO technology using cooperative spectrum sensing is a useful way to reduce error and improve the system gain. In this paper, this kind of scenario is used to provide better spectrum utilization in rural areas. The proposed system model is described for Nakagami-m fading model. Graphical analysis of detection probability is shown which is obtained from(More)
In this modern age of high spectral efficiency, Orthogonal Frequency Division Multiplexing (OFDM) has gained a great importance in the field of wireless communication. In this paper, first we have shown a useful comparison for different modulation order in vehicular environment. Next, we have proposed a modified scheme for fast moving environment and on the(More)
The study of relays with the scope of energy-harvesting (EH) looks interesting as a means of enabling sustainable, wireless communication without the need to recharge or replace the battery driving the relays. However, reliability of such communication systems becomes an important design challenge when such relays scavenge energy from the information(More)
Orthogonal Frequency Division Multiplexing (OFDM) has been one of the well distinguished technologies in wireless communication in terms of its robustness and high delivery speed. In this paper, we have performed an effective comparison on the basis of various OFDM transmission schemes and our proposed scheme to examine the most effective one in terms of(More)
Present day, the internet telephony growth is much faster than previous. Now we are familiar with digitized packet of voice stream. So, we have required VOIP communication. SIP is one type of VOIP protocol. This one has a SIP proxy. There have one of the important communication environment Wireless LAN (WLAN). WLAN have different radio link standard. Here I(More)
