Kertas kerja ini mencadangkan kaedah untuk meningkatkan ketepatan anggaran pemalar pengecilan yang diperoleh dengan menggunakan teknik spektrum silang. Dalam teknik spektrum silang, sampul surat anggaran tindak balas impuls berubah bentuk kerana penggunaan tetingkap masa. Akibatnya, anggaran tindak balas impuls mereput lebih cepat daripada tindak balas impuls sebenar, dan pemalar pengecilan yang diperolehi oleh tindak balas impuls yang dianggarkan menjadi lebih besar daripada nilai sebenar. Kertas ini mula-mula menerangkan bagaimana pemalar pengecilan berubah dalam proses anggaran tindak balas impuls. Seterusnya, kami mencadangkan kaedah untuk meningkatkan ketepatan anggaran. Kesan kaedah yang dicadangkan disahkan oleh simulasi komputer.

Manabu FUKUSHIMA, Takatoshi OKUNO, Hirofumi YANAGAWA, Ken'iti KIDO, "Improvement of the Accuracy in Attenuation Constant Estimation Using the Cross-Spectral Technique" in IEICE TRANSACTIONS on Fundamentals,
vol. E82-A, no. 4, pp. 626-633, April 1999, doi: .
Abstract: This paper proposes a method of improving the accuracy of the attenuation constant estimate obtained by using the cross-spectral technique. In the cross-spectral technique, the envelope of the estimated impulse response is deformed due to the use of a time window. As a result, the estimated impulse response decays more rapidly than the real impulse response does, and the attenuation constant obtained by the estimated impulse response becomes larger than the real value. This paper first describes how the attenuation constant changes in the process of impulse response estimation. Next, we propose a method of improving the accuracy of the estimation. The effect of the proposed method is confirmed by computer simulation.
