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 Quadrature Amplitude Modulation(QAM) and PSK modulation 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.
