Abstract

In this work, coherent modulation Terahertz communication link with pointing errors are analyzed for the Gamma-Gamma turbulence channels. The high-precision bit error rate and outage probability expressions for the Gamma-Gamma turbulent channel using coherent quadrature phase-shift keying signal are derived, and the bit error rate and outage probability are analyzed for its asymptotical property. The results show that our series error rate expression can accurately evaluate the system performance. It has high precision in estimating and predicting actual error rates.
