Variable length error correcting (VLEC) has gained very high importance in recent years. In this paper, focusing on inducing the best execution of variable length error correcting (VLEC) as a Source coding and error correcting in single step with16-QAM orthogonal frequency division multiplexing (OFDM) for Long Term Evolution (LTE). The execution of these codes with maximum likelihood decoding algorithm built on a modified edition of the viterbi decoding algorithm is examined and a comparison between cascade source-channel coding with same parameters is created. Also VLEC was compared with turbo code as channel coding. The scheme is implemented by (MATALAB R2015a) technical programming language.
