In each of these cases, communication is carried out using a specified carrier frequency, with various modulation techniques used to transmit the desired information, whether it be voice, data, or ...

Therefore, they require more bandwidth to achieve jammer protection. The same type of digital modulation techniques are used in a spread spectrum system, but a pseudorandom code at a much higher bit ...

Especially in the frequency bands below 1 GHz, you might find yourself interfacing with a module at really low level, where you might be tuning modulation parameters. The following overview should ...

Most high-throughput data networks rely on optical transmission methods to transfer data, with two dominant modulation techniques: 4-level pulse amplitude modulation (PAM4) and coherent modulation.

CEA-Leti researchers have developed the first reported device, which can sense light and modulate it accordingly in a single device using a liquid crystal cell and a CMOS image sensor.
