Abstract :
This paper proposes a new channel equalization method with the combination of noise reduction with average samples and auto adapted FIR filter. It illustrates the principle and the performance of this method and shows the satisfying GMTI results in low signal-noise ratio. Compared with some other channel equalization methods beyond training, the proposed method in this paper can achieve better results and overcome some defects of theirs.
