Information can be sent from a transmitter to a receiver by means of modulation and demodulation, respectively, whether those signals are light waves moving through optical cables, radio waves through ...

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.

the modulation/demodulation process, and transmission performances of the prototype transmitter and receiver. We also indicate that 8K ultra-high definition television (UHDTV) with an encoded bit rate ...

It represents a simplified version of the WiFi (802.11) PHY layer, including packet construction at the transmitter ... Receiver Implementation (OFDM_RX.m): Performs packet detection, synchronization, ...

But for a weekend project, [Vinod.S] took the ultrasonic transmitter ... the ultrasonic receiver, followed by a transistor amplifier for the modulated wave, then a diode for demodulation, another ...

Abstract: The LoRa modulation ... signals at the transmitter side, providing a simple algorithm that leverages digital signal processing techniques to reduce the modulator complexity. Secondly, we ...

This is a basic DCF77 receiver for GNU Radio, containing: signal demodulation and detection of the DCF77 OOK signal with an SDR using GNU Radio (and Python modules) signal demodulation and detection ...

Phase shift modulation (PSM) and demodulation are techniques for encoding and decoding information in the phase of a carrier signal. They are widely used in communication systems, such as radio ...
