Objective: To simulate QPSK signals, focusing on modulation, transmission, and demodulation processes. Current Status: This project is under active development. The notebook includes initial work with ...

16 QAM modulation and demodulation mode has the advantage of high noise tolerance and superior anti-noise performance, and it is suitable to work in the environment with large signal-to-noise ratio ...

HOLZKIRCHEN, Germany -- Sept. 20, 2016 --WORK Microwave, a leading European manufacturer of advanced satellite communications equipment, today announced a new single-carrier Wideband Demodulator that, ...

He’s broken down the modulation and demodulation circuits into their basic op-amp stages with examples of what the signal should look like on a scope after each stage. That’s the beauty here.

The authors describe a subharmonically pumped QPSK modulator and demodulator using pairs of beam-leaded Schottky diodes and appropriate high-pass and low-pass filters on dielectric substrates. A ...

The design process involved the following steps: Circuit Simulation: The circuit was simulated in LTspice software.; PCB Design: Schematic and layout routing were completed using PCB design ...

Now, a demodulator is much harder than a modulator. The specification tells you exactly what signal to transmit, so "all" you have to do is build a piece of equipment that codes the signal in the ...

This demodulator is suitable for the quadrature phase-shift keying (QPSK) modulator previously published by the same author, "Novel Low-Cost QPSK Modulator Needs No Adjustments" (electronic design ...

In this paper, BPSK modulator and demodulator are purely design by using Hardware Description Language (VHDL) and implementing it on Spartan 3E FPGA kit. Subscribe to the Developer Insider Newsletter ...
