High Peak to Average Power Ratio (PAPR) of the transmitted signal is a serious problem in multicarrier modulation systems. In this paper a new technique for reduction in PAPR of the Multicarrier Code Division Multiple Access (MC CDMA) signals based on combining the Discrete Transform either Discrete Cosine Transform (DCT) or multi-resolution Discrete(More)
Code Division Multiple Access (CDMA) is currently dominating air interface technique used in wireless communications for 3G and 4G systems. Multicarrier CDMA has become the focus of current research interests in wireless digital communication. Multi carrier CDMA, Orthogonal Frequency Division Multiplexing (OFDM) techniques used for 3rd Generation and 4 th(More)
In this paper, a new multi tone test signal generation method is presented with different frequency tones uniformly distributed across a wideband spectrum. It employs OFDM (Orthogonal frequency-division multiplexing) spread spectrum technique to allow users to define signal parameters with a great flexibility as per test requirements.OFDM is a well known(More)
Abstract: Modular adder is used in Residue Number System (RNS) addition. Moduli set with the form of 2-21(1≤ k≤ n-2) can offer excellent balance among the RNS channels for multi-channel RNS processing. In this paper, a Finite Impulse Response (FIR) filter using a novel algorithm and its Very Large Scale Integration (VLSI) implementation structure are(More)
Fault tolerant architecture is used to increase the reliability and decrease the fault rate. Fault tolerant in arithmetic operations mainly deal with addition, subtraction, multiplication division. In this paper mainly focused with adders. These adders are half adder, full adder, ripple carry adder, carry look ahead adder, conditional sum adder. Kogge stone(More)
A significant problem in Multicarrier Code Division Multiple Access (MCCDMA) system is the possibility of high Peak to Average Power Ratio (PAPR). This is due to the cumulative sum of N subcarrier peaks in the transmitted signals which reduces Power efficiency, resolution and battery life. In this paper a technique is proposed to make use of Inverse(More)
The main aim of this project is to find the authenticationof user’svoice based on FPGA voice processing. Voice samples of authorized users will be trained and stored in VLSI hardware. Whenever the user speaks in front of microphone, the incoming voice compares with the trained voice samples and if they get matched to the matching score of 98%, then the(More)
INTRODUCTION Central venous pressure (CVP) measurement is essential in the management of certain clinical situations, including cardiac failure, volume overload and sepsis. CVP measurement requires catheterization of the central vein which is invasive and may lead to complications. The aim of this study was to evaluate the accuracy of measurement of CVP(More)
