Title:
METHOD AND APPARATUS FOR GENERATING OFDM TIME-DOMAIN SIGNAL
Document Type and Number:
WIPO Patent Application WO/2017/148189
Kind Code:
A1
Abstract:
Disclosed are a method and apparatus for generating an OFDM time-domain signal, for use in effectively withstanding impulse interference. The method comprises: mapping data onto a subcarrier in a target set to generate an OFDM frequency-domain signal; and performing M-point inverse Fourier transform on the OFDM frequency-domain signal to generate an M-point OFDM time-domain signal; if the M-point OFDM time-domain signal is a complex OFDM time-domain signal, the target set comprises any one of the following sets: a set consisting of the nkth subcarrier, a set consisting of the (nk+1)th subcarrier, a set consisting of the (nk+2)th subcarrier,..., and a set consisting of the (nk+n-1)th subcarrier; if the M-point OFDM time-domain signal is a real OFDM time-domain signal, the target set comprises any one of the following sets: a set consisting of the nkth subcarrier and a set consisting of the (nk+n/2)th subcarrier, wherein n is a factor of M and is greater than 1, k is one or more integers in [0, (M/n)-1].
