Title:
SECURE LTF SEQUENCE DETERMINATION METHOD AND RELATED APPARATUS
Document Type and Number:
WIPO Patent Application WO/2023/174353
Kind Code:
A1
Abstract:
The present application provides a secure long training field (LTF) sequence determination method and a related apparatus. The method comprises: a sending end determines a sequence X on the basis of a modulation mode; the sending end performs fast fourier transformation (FFT) on the sequence X, and performs normalization processing on a result obtained after FFT, so as to obtain a sequence Y; and the sending end determines a secure LTF sequence M on the basis of the sequence Y. Hence, the sending end determines the sequence X from a time domain on the basis of the modulation mode, and then determines the secure LTF sequence M on the basis of the sequence X. The sequence X determined by the sending end from the time domain on the basis of the modulation mode has a low peak to average power ratio (PAPR), and thus, the secure LTF sequence M determined on the basis of the sequence X also has a low PAPR.
