The trellis coding technique is applied to line-coded baseband digital transmission systems. For R = n / n + 1(n = 1,2,3) coding rates, a new codeword assignment model is proposed to accomplish basic requirements for line coding in which each length n binary data sequence is encoded into a length n + 1 ternary (+, 0, -) line codeword chosen among the code alphabet with 2n+2 elements. Assuming Viterbi decoding, the system error performance is improved by increasing the free Euclidean distance… CONTINUE READING
