   2 Performance Analysis of LTE and IEEE 802.16 Wi-Max in Terms of Service and Cost Via MATLAB; Scenario Based ROF Amalgamation as Backhaul Technology.
Hitesh Kumar, Nadia M. Ansari, Rizwan Iqbal, Naveed Ghani

The possibilities for fiber optics are nearly endless because they are flexible under extreme conditions and the signal do not distort easily. Wireless technology has introduced high speed internet accessibility through wireless broadband. Radio over fiber; the integration of microwave and optical networks is the potential solution for reducing cost in terms of equipment, running finance and capacity enhancement. Radio over fiber, a supreme technology for the amalgamation of wireless and wired environment, because it combines the best parameters of two mostly used communication technologies. The purpose of this paper is to analyze the performance of ROF as a backhaul technology when compared to the traditional optical fiber in wireless environments like LTE & IEEE 802.16 WiMAX. Radio technology over optical fiber as a medium can prove to be the next generation solution. The analysis is then used to identify ROF feasibility as a backhaul technology for LTE and WiMAX. Optical and ROF network is deployed using MATLAB for acquiring the results through simulation to prove the hypothesis.

   3 FPGA Implementation of Modified Median Filter for Impulse Noise Removal From Image.
Panchami Padmasana, Mihir Narayan Mohanty, P. Kabisatpathy

Acquired images are often noisy in nature as well as illumination is non-uniform. Techniques have been developed since a long period for reducing noise which is highly essential. Still there is the challenge to work in this field. In some binarization-based approaches the binarization and thinning process are preceded by a smoothing operation. The paper proposes a modified median filter to reduce noise and can be necessary for pre- and post-processing. The nonlinear filters design and analysis is much difficult than for linear filters. Again the implementation part is even difficult for this filter. The attempt has been taken to design and verify for noise removal. The proposed method is based on modified median filter and simultaneously it has been implemented in VHDL for FPGA architecture.

   4 A Comprehensive Review on k-Means Clustering Algorithm in Neural Networks.
Neha, Neelam Chaudhary, Tanvir Singh

Neural Networks is known for its ability to derive the complicated data to extract the complex information in the form of particular patterns which can’t be noticed by human beings or by any other computing technique. In neural networks, there are various approaches of pattern recognition, which are list down in this paper, and out of them, k-Means Clustering Algorithm is discussed with simulation results, pros-cons and applications.

   5 Spectrum Sensing Using Energy Detection With Sensing Time for Cognitive Radio Networks.
Tulika Mehta, Kirti Arora, Varun Sharma, Bharti Papnai, T.L Singal

In this paper we adopt DSA using cognitive radios and improving the spectrum sensing performance. The inefficiency in spectrum usage brings the requirement of this communication paradigm.In
Cognitive radio networks there are various techniques for spectrum sensing, selecting the appropriate technique and maximizing the efficiency in spectrum sensing plays a major role in getting a desired frequency band for the unlicensed user without outside interference. This paper also provides detailed study on the CR operational requirements, spectrum sensing techniques and all the scenarios of interference are discussed.
