Performance analysis of channel impairment in high data rate satellite communication service

This paper presents a performance analysis for channel impairments that affect the service quality of a high data rate satellite communication system. Based on the modeling of group delay and nonlinear characteristics that severely affect the service quality, the system performances are analyzed for various data rate services via the Ka-band satellite channel. As the transmission data rate is increased, the degradations due to these channel impairments increase. The linear component of the group delay and the AM-AM component of the nonlinear characteristics severely affect the system performance.
