Angle modulationmodulation indexblind estimationnon prior knowledgeIn this paper, a new non prior knowledge estimator of the modulation index of angle modulated (AM) signals is proposed. It consists in estimatin
modulation indexdoi:10.1007/1-4020-0613-6_11733In angle modulation, the ratio of (a) the frequency deviation of the modulated signal to (b) the frequency of a sinusoidal modulating signal. Note:The modulation index is numerically equal to the...Weik, Martin H.Springer US...
Figure 3 shows amplitude spectra for a sinusoidally angle-modulated carrier for various values of the modulation index β. Note that the spectrum is negligible beyond a certain frequency separation from the carrier. A rule of thumb often used to estimate the transmission bandwidth, BT, required for...
