Design of Transmitter and Receiver to Reduce PAPR and ISI in Multi-Carrier OFDM System: A ReviewBy Himanshu Monga
Abstract: In wireless communication, concept of the parallel transmission of symbols is used to achieve high throughput and better transmission quality. Orthogonal Frequency Division Multiplexing (OFDM) is one of the techniques for parallel transmission and it converts frequency selective fading channel into N flat fading channels, where N is the number of sub-carriers. orthogonality is maintained by keeping carrier spacing multiple of 1/Ts by using Fourier transform methods, where Ts is …

Encrypted Visible light communication for optimum performanceBy Himanshu Monga
Abstract: Visible light communication (VLC) is regarded as the relatively secure communication when compared with other wireless communications using radio frequency (RF). The original visible signal sending from the lamp can be first received by the proposed light encrypter. The information can be encrypted and then emitted. The light encrypter acts as an encryption gateway for signals in the optical domain. The rolling shutter effect of the complementary metal–oxide semiconductor (CMOS) …

PAPR REDUCTION MEHODS FOR MULTI CARRIER MODULATION SCHEMES USED IN NEXT GENERATION WIRELESS NETWORKS- A REVIEWBy Himanshu Monga, Pooja Mehta
Abstract: Multicarrier modulation is need of today’s Wireless communication networks. Various multicarrier modulation schemes have been developed in the past few years orthogonal frequency division multiplexing (OFDM), Filter bank multicarrier modulation (FBMC) and Universal filtered multicarrier (UFMC) are some of them. These techniques provide numerous advantages like multiple user scheduling, robustness against multipath propagation, high quality of service etc. One of the major drawbacks of MCM is higher PAPR and a …

A survey- Congestion Evasion in MANETsBy Himanshu Monga
Abstract: The paper addresses the RED active queue management technique used in most of the networks for managing the queue efficiently. Secondly it proposed a Gaussian (G-RED) and modified Gaussian function based RED (MG-RED) algorithm. It is presented that the Gaussian and modified Gaussian function based RED algorithm outperforms the traditional RED algorithm in terms of throughput, packet delivery fraction and number of packets dropped

Enhancement K-Mean Algorithm (EKM) for Image Processing in MATLABBy Himanshu Monga
Abstract: In this paper, a new segmentation scheme for the white blood cells from microscopic images is proposed. This is based on the K-means clustering technique. The RGB test images are converted to the L*a*b color space, and then the two color machinery (a and b) are used as features to the K-means clustering algorithm. The success of image analysis depends on segmentation reliability. The accurate partition of the image into …

Review – An approach to steganography techniqueBy Himanshu Monga, Neha Garg
Abstract: Steganography is the technique that provides the base for secure communication. It is the art of hiding information in some other means of false medium for making a possible secure communication. The information to be hidden can be of any form such as text, image and video etc. and so the cover medium. Unlike cryptography, in steganography after the data is successfully hidden it is not even visible to the …

Congestion Control in WDM NetworksBy Himanshu Monga
Abstract: Because of enormous transmission of information through optical strands, congestion happened routinely and it turned into a major bottleneck to the stream of information in any procedure. Numerous techniques are there to keep away from congestion however those systems for the most part include colossal expense connected with quality certification. These systems are relevant to the zone which is rich in base and assets, however these procedures are extremely hard …
