摘要： Provided are a satellite VSAT apparatus and a control method thereof. The satellite VSAT apparatus according to an exemplary embodiment of the present invention can switch a modulation type of a signal to be transmitted from an indoor unit (IDU) to the outdoor unit to a linear or non-linear type in a case in which outputting of a transmitted signal is not controlled to an outdoor unit due to limitations, that is, there is no function such as an automatic signal level control in a block up-converter (BUC), a case in which transmission output limitation is large due to a lot of interference requirements for an adjacent channel, a case in which the number of adjacent channels (carriers) is large, or a case in which adjacent channel interference is large due to a frequency in a satellite multi-beam environment and polarization reuse, in a satellite VSAT apparatus system which aims at a low-priced user terminal.

摘要： Disclosed is a demapping method of a soft-decision of an efficient soft determining scheme which is applicable to a DVB-2 satellite communication system. The soft-decision demapping method for a digital signal received through a transmission channel in a communication system using a phase shift keying (PSK) scheme includes: selecting reference symbols in an area having a higher probability than a predetermined probability that the received signal will be positioned among all reference symbols on a constellation diagram using a most significant bit (MSB) value of the received signal; and acquiring a maximum value of a log likelihood ratio (LLR) for the selected reference symbols.

摘要： The present invention separates inputted triple play IP data into Internet and TV data and voice (VoIP) data, encodes the Internet and TV data permitting a long delay time according to the existing DVB-S2 standard, and encodes the voice data permitting only a short delay time according to a DVB-RCS+M standard based 4K mode. Each encoded data is subjected to the orthogonal modulation and the orthogonally modulated voice data is subjected to a direct sequence spectrum spread according to a spreading factor. The spread spectrum signal is multiplexed in a SCPC frequency division multiple access (FDMA) scheme so as to overlap with frequencies allocated to each user.
