Title:
MODULATION ORDER ESTIMATION METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/035761
Kind Code:
A1
Abstract:
Provided in embodiments of the present application are a modulation order estimation method and device. The method comprises: performing decimation on a first baseband signal of a digital signal corresponding to a non-linear modulation signal to obtain a second baseband signal of the digital signal; performing frequency shift compensation on the second baseband signal; and acquiring, according to the second baseband signal after the frequency shift compensation, a modulation order of the non-linear modulation signal. The embodiments of the present application improve accuracy of an estimated modulation order.
