Abstract
Official abstract text for this publication.
Provided are a modulation method and a demodulation method for satellite communication using a widespread signal-to-noise ratio (SNR), the method including: adding a dummy frame to a broadcasting/communication signal frame for signal transmission of a digital video broadcasting-satellite second generation (DVB-S2) modulator; verifying a spreading factor; adding the same physical layer header to the broadcasting/communication signal frame to which the dummy frame is added, repeatedly the number of times corresponding to the verified spreading factor; and repeating the same data, for example, PL frame data as the physical layer header.
First claim
Opening claim text (preview).
What is claimed is: 1. An operation method of a modulator in which a band spreading function is added, the method comprising: adding a dummy frame to a broadcasting/communication signal frame for signal transmission of a digital video broadcasting-satellite second generation (DVB-S2) modulator; verifying a spreading factor; and adding the same physical layer header to the broadcasting/communication signal frame to which the dummy frame is added, repeatedly the number of times…
