MIMO radar transmits quadrature signal. It forms a low gain and wide beam which has strong anti-interference ability in the space. The modulation and demodulation circuits of QPSK have been designed ...

Targeting the differential RF/microwave circuit design methodology for improved broadband wireless data transmission, a novel differential 7.5 GHz six-port modulator and demodulator pair was designed ...

AM Modulation: Generating an AM signal using a switching modulator circuit and evaluating it in both the time and frequency domain. AM Demodulation: Recovering the original message signal using an ...

Phase-modulation and -demodulation techniques are more complex than modulation and demodulation based on amplitude and frequency. However, they provide the benefit of higher data rates for the amount ...

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.

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 ...

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

Demodulator makes low-cost optical trackerSteven Sarns, Kesta Technology Inc, Wheat Ridge, CO A project required building a synchronous-demodulator circuit to track a line drawn on paper.

Digital modulation/demodulation formats provide options in terms of bandwidth efficiency, power efficiency, and complexity/cost when meeting a modern communications system’s data-transfer needs.
