In contrast to the sophisticated implementation of Binary Phase Shift Keying (BPSK) transmitter using Application Specific Integrated Circuit (ASIC), mixer, and Local Oscillator(LO) for carrier signal; Software Defined Radio (SDR) provides a high performance, efficient and re-configurable platform to integrate all these individual functions of BPSK transmitter. This paper presents a tutorial exploitation to design ...

Automation is the Technology Concerned with Application of Mechanical, electronics & computer based systems to operate & control production. Due to advancement in technology the people have seen atomization of many things. They have seen an atomized vending machine which will serve a hot or soft drinks, Chocolates &many things. There is automation of tickets ...

The continuous improvement in development of Linux for the Embedded system makes it secure, table and reliable. Embedded Linux plays an important role in the embedded field. Linux has been widely used in embedded system due to its small size kernel, stable performance, versatility and low prize. This paper describes the transplantation of the Linux ...

In the present paper wireless sensor network for hierarchical network protocol of LEACH and HEED this is theory concept that how to data gathering. The authors’ protocol aims to dynamically change the data Gathering period according to the Gathering quality. The timing scheme will find the minimum Gathering period that satisfies the sink’s request. This ...

Peak-to-Average Power Ratio (PAPR) is an important parameter for the analysis of Orthogonal Frequency Division Multiplexing (OFDM) signals. CCDF curves are known to have great importance in the study of signal performance on the basis of power level. This paper presents the CCDF performance of the OFDM signal with different number of carriers. Simulation is ...

A new wireless sensor networking technology, DASH7 uses the ISO/IEC 18000-7 standard for active RFID. It operates in the 433 MHz unlicensed spectrum. DASH7 provides many advantages over other wireless technologies such as multi-year battery life, dynamic range of up to 2 Km (potentially farther) etc.DASH7 is the name of the technology promoted by the ...

The purpose of this paper is to increase the security that customer use the ATM machine. Once user’s bank card is lost and the password is stolen, the criminal will draw all cash in the shortest time, which will bring enormous financial losses to customer, so to rectify this problem the authors are implementing this ...

In this paper VHDL implementation of 8-bit Arithmetic Logic Unit (ALU) is presented. The design was implemented using VHDL Xilinx Synthesis tool ISE 13.1 and targeted for Spartan device. ALU was designed to perform arithmetic operations such as addition and subtraction using 8-bit fast adder, logical operations such as AND, OR, XOR and NOT operations, ...

In this paper, a study of the behavior and correlation between High Possible Frequency (HPF) and Optimum Maximum Usable Frequency (OPMUF) parameters for the communication links distributed over Middle East Region were made. A mutual correlation equation between the two parameters has been suggested. The analytical test of the monthly and annual variation of the ...

Free Space Optics is the technology which implies the line-of-sight link for the transfer of data between two distant points. The beam of light is used to provide optical connection that can transmit and receive data. The performance of the modulation techniques-Binary Phase Shift Keying (BPSK) and Quadrature Phase Shift Keying (QPSK) are studied in ...
