摘要: A cooperative transmission method includes: a first operation of coding, by a source node, a message desired to be transmitted according to a first encoding scheme to generate a first codeword and transmitting the first codeword to a relay node and a destination node; a second operation of decoding, by the relay node, the first codeword which has been received from the source node, coding the decoded message according to a second coding scheme to generate a second codeword, coding a part corresponding to parity of the second codeword according to the first coding scheme to generate a third codeword, and transmitting the third codeword to the destination node; and a third operation of decoding, by the destination node, the first codeword which has been received from the source node and the third codeword which has been received from the relay node, combining the message generated by decoding the first codeword and the parity part of the second codeword generated by decoding the third codeword to generate a fourth codeword according to the second coding scheme, and decoding the fourth codeword to estimate the message desired to be transmitted.

摘要: In an error data removing apparatus and method by decoding delay in a DTV system which employs a decoder of the VSB standard, respective segments or respective fields are divided into area 1 and area 2 using a starting point of decoded data as a reference to provide the decoded data of said area 1 section without involving delay and provide the decoded data of said area 2 section by delaying as long as a sync signal. A memory is utilized as the decoded data delay apparatus, and at this time, a value of a counter used for generating an address for reading/writing of the memory is utilized to delay the segment sync signal and field sync signal as required without separately using flip-flop or memory.
