英文摘要	The satellite communication is an important approach of remote education. However, the linear distortion of the satellite decreases the spectrum effectiveness, especially for the system with high-order modulation. Thus, one hybrid factor-graph equalization (HFGE) algorithm is proposed to compensate the linear distortion with less complexity. This HFGE is comprised of a linear equalizer (LE) and a factor-graph equalizer (FGE). The LE in HFGE preprocesses the received signals to offset most of the small multipath, and the FGE deals with the residual large multipath. Simulation results show that HFGE can converge to lower error rate and has better performance than LE or FGE algorithms over the channels with group delay and amplitude response. ? 2014 WIT Press.; EI; 0
