Abstract :
We introduce a new method for enumerating codewords that can be applied to DC2-constrained channels. Based on this method, two efficient algorithms for evaluating the number of codewords with specified characteristics are developed. Computer calculation results show that these algorithms are significantly more computationally efficient than other techniques developed to date
