Mean User Data Throughput Assessment From A Public UMTS/HSPA Network
Abstract: The demands of packet data communication and applications have resulted in several improvements over the original WCDMA Release 99. The downlink was improved in Release 5 with high speed packet data access (HSDPA), which provided high speed shared channel with fast link adaptation and scheduling, hybrid ARQ, and a short 2 ms transmission time interval (TTI). The corresponding uplink enhancements were done in Release 6 with high speed packet data …

A New Optimal Biphase Pulse Compression Codes based on Cosine Mapping
Abstract: In proposed method a new optimization algorithm based on cosine mapping is introduced for radar pulse compression. The algorithm generate optimal chaotic biphase sequence having good autocorrelation and cross correlation properties. The sequence produces inherently small side lobes in autocorrelation function (ACF) of matched filter. Reduced values of side lobe level signify the optimal values of merit factor (MF) and peak side lobe level (PSL) and hence enhancement in radar …

BER Analysis for Wireless Cooperation Network based OFDM Systems
Abstract: The cooperative wireless network uses the broadcast nature of the wirelessThe cooperative wireless network uses the broadcast nature of the wireless propagation channel where the involved nodes share resources in a network. It has emerged as a promising approach to increase spectral and power efficiency and network coverage and to reduce outage probability. In this paper the estimation of error rate performance for wireless transmission is made by analyzing the …

Millimeter Wave Modulation for 5G Communication
Abstract: The universal bandwidth shortage for providing high data rate in gigabit per second has motivated the study of Underutilized millimeter wave band. It provides frequency spectrum for future fifth generation mobile communication networks. Propagation of millimeter wave in environment is affected by atmospheric conditions like rain, fog, cloud etc. and it is mostly affected due to presence of rain and rate of rainfall. Our objective is to develop modulation technique …

Nonlinear Fusion Techniques Comparative Analysis For The Confiscation of Reconnaissance Effects from the Fused Image
Abstract: Image fusion is the process of combining relevant information from two or more images into a single image. It provides a useful tool to integrate multiple images into a composite image. The resulting image will be more informative than any of the input images. Recently the new problem found with the fused image is about reconnaissance effects are present which are inexorable while smearing to the medical field. For solving …

Performance comparison of DWT OFDM systems and FFT OFDM system over an AWGN channel
Abstract: Orthogonal frequency-division multiplexing (OFDM) is a method of encoding digital data on multiple carrier frequencies. The OFDM systems till now have been used as what we can call as a conventional OFDM incorporates Inverse Fast Fourier Transform (IFFT) blocks in their transmitters and FFT (FFT) blocks in their receivers. Recent research shows that the use of Inverse Discrete Wavelet Transform (IDWT) in place of IFFT and Discrete Wavelet Transform (DWT) …

Design and Analysis of Two Stage Fully Differential Telescopic Operational Amplifier and Two Stage Fully Differential Folded Cascode Operational Amplifier
Abstract: This paper presents a design methodology of a two stage fully differential telescopic operational amplifier. Similar analysis is carried out for the two stage folded cascode operational amplifier and results are compared at 180 nm technology node. Here effort is made to make the unity gain frequency and the slew rate same of both the respective two stage amplifiers. The purpose of such an effort is to carry out a …
