| Abstract: | Fruitful developments in the signal reconstruction from its spectral magnitude are witnessed whereas the parameter solution of MA model encounters difficulties. The authors establish the relation between the parameter solution of MA model and the signal reconstruction from its spectral magnitude, and link two of them together. Thus, all the theories and algorithms in signal reconstruction from its spectral magnitude should be applicable to solving the parameters of MA model. |
