Last month, I introduced an 8-PSK example. As I showed, the 8-PSK example appears to be the combination of coding and modulation that's the basis for Trellis-coded modulation (TCM). However, it's not ...

Telcoms operator Telstra will adopt a new modulation technique on its Endeavour subsea cable system, that links Australia and Hawaii. Telstra has tested the Advanced Coherent Toolkit (ACT) from ...

An alternative to PSK that is claimed to be a simpler solution is four-level pulse-amplitude modulation (PAM-4). As the name suggests, the data is encoded as four distinct power levels.

The CS67PLUS utilizes Phase Shift Keying (“PSK”) modulation schemes, critical in troposcatter applications for its low peak-to-average power ratio (“PAPR”).

In another study, modulation format conversion between 16-PSK and 8-PSK was achieved in an elastic optical network using a highly nonlinear fibre platform, which significantly enhanced spectral ...

FSK/PSK modulator circuits usually employ analogue components such as VCO (voltage control oscillator), RF Mixer, and Level-shifter, with limited frequency range and whose performance drifts with ...
