Design of BPSK/QPSK Modulator using Verilog HDL and Matlab
Quadrature Phase Shift Keying (QPSK) is a modulation scheme commonly used in wireless communication system and it’s because of its ability to transmit twice the data rate for a given bandwidth. In most cases, the QPSK modulator consumes less power and bandwidth in a modern devices but for a system like satellite and mobile devices where their operations are power limited, this is a problem that...
متن کاملDesign of a low cost BPSK modulator/demodulator for a practical teaching of digital modulation techniques
Teaching the digital transmission techniqueslike other fields of electronicis not always easy : There is classically theoretical courses and practical lessons. The link between the two is often the most important difficulty that appears for the students. An abundant literature on digital wireless, including high mathematical level approaches is available; since a few years, theoretical courses ...
متن کاملLow-voltage, high speed, compact silicon modulator for BPSK modulation.
A low voltage, high speed, compact silicon Mach-Zehnder Interferometer (MZI) modulator for Binary Phase Shift Keying (BPSK) modulation has been demonstrated. High modulation efficiency, VπLπ equals to 0.45V·cm, was obtained in a 1mm length device owing to a higher doping concentration and low-loss traveling-wave electrode. 25 Gb/s non-return-to-zero(NRZ)-BPSK with 6Vpp RF driving signal was ach...
متن کاملinvestigating the feasibility of a proposed model for geometric design of deployable arch structures
deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
A New Design of Fault Tolerant Comparator
In this paper we have presented a new design of fault tolerant comparator with a fault free hot spare. The aim of this design is to achieve a low overhead of time and area in fault tolerant comparators. We have used hot standby technique to normal operation of the system without interrupting and dynamic recovery method in fault detection and correction. The circuit is divided to smaller modules...
