Traditional Power Amplifier design for low power application use various classes of amplifiers such as Class A, Class AB, Class E to avoid output filters that degrades the output efficiency. Class-E PA is a nonlinear switching type PA which can ideally achieve 100% efficiency. Generally the output of the Power Amplifier should match with antenna's 50Ω resistance; this high efficiency has spurred many research interests on the design and analysis of Class-E PAs. The aim of the paper is to design a microwave PA which works in the narrow band range of 2.35-2.45GHz. This paper presents a new Class-E PA with a π-matching output network which produces increased efficiency. The proposed circuit consists of power amplifier stage along with the Pre-driver stage. The Pre-driver stage is an indispensable stage when we refer to the rest of power amplifier. The N-Channel Field Effect Transistor (NFET) Inverter with a serial inductor reduces the power consumption of the switching capacitance of the PA stage is used as the pre driver stage. The PA stage realised by NFET. In order to increase the efficiency of PA a parallel inductor is introduced to the conventional Class-E PA structure. The Proposed structure needs a supply voltage of 0.5 V. The structure is simulated using the Advanced Design System (ADS) simulator. The output of the simulator produces graph of current with time and voltage with time. The efficiency of the PA is also plotted using ADS. It is possible to achieve increased efficiency when the width of the transistor is reduced. The inductor introduced at the output stage also has an impact on the efficiency of the PA. The proposed PA finds applications in Bio-Telemetry, short distance communications etc.","PeriodicalId":149965,"journal":{"name":"2014 International Conference on Communication and Signal Processing","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123722838","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In MANET each and every process consumes power. Power consumption is one of the most crucial design concerns in Mobile Ad-hoc networks as the nodes in MANET are battery limited. To increase the life time of nodes as well as network energy management is necessary. The life time of a node can be increased when less power is consumed by the nodes during active as well as during inactive communication. In order to increase the life time of a node, traffic should be routed in a way that, power consumption is minimized. DSR is a routing protocol used in MANET. It uses two mechanisms in routing Route Discovery and Route Maintenance. During route discovery it selects the path to establish communication between source and destination. The flooding of routes creates overhead in routing traffic which cause extra consumption of energy. In this paper anew route discovery mechanism is proposed to conserve the energy of nodes during route discovery and data transmission phase compare to original DSR protocol. The proposed work is verified using NS-2 simulator.","PeriodicalId":149965,"journal":{"name":"2014 International Conference on Communication and Signal Processing","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121295614","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Objective is to measured different parameters that are heart rate, respiratory rate, BP. PPG signal is acquired by PPG sensor, microcontroller and RS 232. The acquired PPG signal is displayed in MATLAB. Frequency domain analysis of PPG signal shows a two peaks first at around 0.25 to 0.35 Hz and second at around 1 to 1.5 Hz. FFT at 1Hz relates to 60 BPM and FFT at 0.25 Hz relates to 15 respiratory cycles per minute. For BP Measurement, the pulse height of PPG is proportional to the difference between the systolic and the diastolic pressure in the arteries. The standard blood pressure monitoring instrument is used to calculate correlation coefficient. The arterial blood pressure is calculated based on these coefficients. PPG signal is used to detect blood pressure pulsations in a finger and achieved an accuracy of (0.8 ± 7) mmHg and (0.9 ± 6) mmHg for systolic and diastolic pressure, respectively. The developed PPG based method can be used as a noninvasive alternative to the conventional occluding-cuff approaches for long-term and continuous monitoring of blood pressure, heart rate and respiratory rate.","PeriodicalId":149965,"journal":{"name":"2014 International Conference on Communication and Signal Processing","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114086010","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Firstly the algorithm employs the cross-coupled chaotic skew tent map to perform the shuffling operation, and then uses the fractional order versions of Lorenz's system and Chen's system to disturb image pixel intensity values. Fractional order extensions of the chaotic systems provides a much larger key-space than their original integer order versions. The encrypted image exhibits uniform histogram and a very high entropy for all the three colour channels. Also, the property of zero correlation is satisfied by the intensity values of adjacent pixels in each channel of the encrypted image. Moreover, the algorithm possesses a key-space which is large enough to resist all possible kinds of statistical attacks. Theoretical analysis and experimental results thus demonstrate that the proposed scheme has an excellent efficiency and satisfactory security attributes. However, solving fractional order differential equations is a computationally heavy process. Some efficient computing techniques are successfully employed to deal with this problem, so that the encryption-decryption process is executed reasonably fast.","PeriodicalId":149965,"journal":{"name":"2014 International Conference on Communication and Signal Processing","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127687276","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
