Modulation Performance Analysis of Terahertz Satellite Communication System

Terahertz; APSK modulation; QAM modulation; PSK modulation; Nonlinear channel

The amplitude and phase shift keying (APSK) modulation as a combination of PSK modulation and Quadrature Amplitude Modulation(QAM) method, both reduces the sensitivity of the nonlinear amplifier, but also improve the spectral efficiency, it has been widespread concern in satellite communications. Combining 16PSK, 16QAM modulation performance comparison 16APSK modulation, verify the superiority 16APSK modulation terahertz satellite communication system.
