Definitions of convolution code

Tree code The infinite set of all infinitely long codewords which are obtained for every possible input message sequence applied to a shift register, is called as a (n0,k0) tree code. Constraint length

Constraint length of a shift register encoder is defined as the number of symbols it can atore in its memory. Code tree rate The rate of a tree is defined as the ratio of k0 and n0 R=k0/n0
