Phase Noise Effects on the Performance of High-Order Digital Modulation Terahertz Communication System
文献摘要：
As the carrier frequency goes into the terahertz band,the phase noise of the signal source has increasing impacts on the performance of the communica-tion system.Considering a 16QAM high-order digital modulation terahertz communication system(DMTCS),by comparing the influence of two kinds of local oscillator signal sources with different phase noise characteristics on the bit error rate(BER)performance of the system based on theoretical analysis and experimental research,it is found that the near-end phase noise of local oscillator sig-nal source has a great influence on the BER performance of the DMTCS.The suppression of phase noise of the loc-al oscillator signal source based on choosing loop band-width of the digital phase-locked loop(DPLL)at the re-ceiving end is also discussed.It is found that the negative impacts of phase noise on BER performance of the sys-tem can be efficiently decreased by reasonably selecting the loop bandwidth of the DPLL.
