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)
High Peak to Average Power Ratio (PAPR) of the transmitted signal is a critical problem in multicarrier modulation systems (MCM) such as Orthogonal Frequency Division Multiplexing (OFDM), and Multi-Carrier Code Division Multiple Access (MC CDMA) systems, due to large number of subcarriers. High PAPR leads to reduced resolution, and battery life. It also(More)
Modular adder is used in Residue Number System (RNS) addition. Moduli set with the form of 2 n-2 k-1(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 proposed(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)
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)
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)
