An algorithm for determining if a rate (n l ) /n punctured convolutional encoder is catastrophic is presented. The algorithm determines whether or not the punctured state diagram contains a zero-weight cycle. The punctured encoder is assumed to be obtained from a rate l / b , b 5 n, antipodal (gd = gd = 1, j = 1, 2, e , b ) encoder of constraint length U… CONTINUE READING
