It is necessary to equalize the received signals to weaken serious multipath effects in troposcatter communication systems. According to the multipath channel model in scatter communication systems mentioned in related papers, a low-complexity decision-feedback equalization based on noise-prediction is proposed by partial coefficients of curve fitting prediction in nonlinear decision feedback equalizer when time delay power spectrum is under the condition of exponential decay. Simulation results showed that the method proposed in this paper has a lower complexity as well as good BER performance.
