Waveform comparison in the presence of Gaussian Phase Noise in the sub-THz context
Résumé
Driven by the need of more available frequency bands, an increasing attention has been paid to the use of sub-THz bands, as shown by the author in [1]. In this review of the advances in the THz communications, the author explained that publications have been numerous since early 2000. Communication systems using all-electronics or photonics are using carrier frequencies in the unexpected range of 100 GHz-700 GHz, though the most studied frequency bands lies between 200 GHz and 400 GHz. From this review, researchers have reached over 100 Gbps. These systems used only OOK, QPSK and 16-QAM modulation schemes. Our sudy here is relevant, because it presents an extended study of waveforms in this context.
