Abstract: The present invention relates to a method for demodulating a variable pulse position modulation (VPPM) signal, which demodulates data from the VPPM signal. The method for demodulating the VPPM signal according to the present invention comprises the following steps: a sampling step of sampling a received VPPM signal; a measuring step of measuring the brightness of the sampled VPPM signal; generating mask 1 and mask 0 by using the measured brightness of the VPPM; a synchronizing step of synchronizing the generated mask 1 and mask 0 to the VPPM signal; and a demodulating step of demodulating data for the VPPM signal by using the synchronized mask 1 and mask 0.
