Abstract

In this thesis, firstly, based on the MATLAB/Simulink platform, the simulation channel module for terahertz wave (300GHz) communication is established based on the MPM modeled clear sky atmospheric channel,and Hamming (7,4) and RS (188,204) channel compilation code and 2FSK, QPSK, 16QAM signal modulation and demodulation, which are commonly used in the traditional frequency bands, are selected to form a simulation model of terahertz communication system. By comparing the BER analysis, it is found that Hamming (7,4) coding and QPSK modulation technology can achieve relatively low BER, but the traditional modulation and coding method has poor performance in terahertz communication at low SNR.Then,the experiments conducted on the wireless communication system controlled by LabVIEW on the PXIe platform confirmed and validated the conclusions derived from the simulations.
