What is the rate of the ldpc code defined

Reference no: EM131249040

(Rate of LDPC) A binary block code that translates k message bits into codewords of length n is said to have rate R = k/n (which is k bits of information for every n transmitted binary digits. Shannon's theorem states that for R < C (where C is the capacity of the channel) and > 0, there is a code of some finite length n that attains rate R with a probability of error less than.
