Tanner graphs play a central role in the design and decoding of low-density parity-check codes. They have also been applied to the construction of longer codes from smaller ones. Both encoders and decoders employ these graphs extensively. Let R be the rate of the resulting linear code, let the degree of the digit nodes be m and the degree of the subcode nodes be n . If each subcode node is associated with a linear code (n,k) with rate r = k/n, then the rate of the code is bounded by R \\geq 1 - (1 - r)m \\, Michael Tanner's Original paper Michael Tanner's page",
