The empirical Bayes test (EBT) is proposed for testing H0 : θ ≤ θ0 ↔ H1 : θ > θ0 in the truncated-type distribution families. It is found that the EBT proposed is obtained asymptotically optimal and its convergence rate is also obtained.



Finite pulse method for harmonic retrieve

November 1999

To implement retrieve of harmonic signal, the pulse function was constructed first to make the convolution of original signal and the pulse function be zero. The high order algebraic equation was derived. The optimized solution of the coefficients of the equation was solved, that is the generalized characteristic vector corresponding minimum generalized characteristic value. Then, the estimation of frequency, amplitude, phase and decrement factor for the harmonic components of the signal was obtained. The simulation results under the different ratio of signal to noise have shown that the finite pulse method is quite effective.
