Analysis of real harmonic process noise background symmetry between ARMA model coefficients, and as a constraint to join ARMA spectral estimation method solving process, and thus an improved method of sinusoidal frequency estimation. Theoretical analysis and Computer simulations show that under conditions of low SNR for sinusoidal signal parameter estimation, precision and stability of this algorithm are superior to only using total least squares method (SVD-TLS) for ARMA spectrum estimation methods.
