Abstract: A decoding method for detecting a PLSC(Physical Layer Signaling Code) of a satellite broadcasting system frame is provided to improve reliability of PLSC decoding by performing (32,6) Reed-Muller decoding in parallel and reduce the quantity of calculations. A symbol vector is received, and a sum vector and a difference vector of a symbol pair are obtained from the received symbol vector. (32,6) Reed-Muller decoding using Hadamard matrix is performed on the sum vector and the difference vector to estimate a message bit of the sum vector and a message bit of the difference vector. The message bits are PLSC-encoded and modulated(403,404). A difference between the received symbol vector and a symbol according to the sum vector and a difference between the received symbol vector and a symbol according to the difference vector are calculated and compared to each other(405,406). When the difference according to the sum vector is smaller than the difference according to the difference vector, it is determined that Reed-Muller codeword is repeated. When the difference according to the sum vector is greater than the difference according to the difference vector, it is determined that Reed-Muller codeword is inverted.

The stream adaptive unit performs a padding and base-band scramble and forms a base-band frame. The turbo coding unit forms a forward error correction frame by applying a turbo coding to the base-band frame. The mapping unit determines a bit mapping based on a state of a transmission channel. The physical layer framing unit forms a physical layer frame by inserting a header and a pilot symbol into the forward error correction frame.
