Implementation of convolutional encoderAbstract: DN504 FEC of FEC: linear block codes (BCH, ReedSolomon, etc) and convolutional codes. An (n,k) linear block encoder takes kbit block of message data and appends nk redundant bits algebraically related to the k message bits, producing a nbit code block. There are 2k valid code words, which is far less than the 2n possible code words, and a good linear block code is one in which the minimum distance dmin, the minimum , dimensionless ratio r = k/n is called the code rate.
