| Abstract(in English) | We propose a new error correction method using Hidden Markov Models (HMMs). The code sequence is decoded by a maximum likelihood estimation (ML). The measure for the ML consists of two probabilities extracted from a source model specified with HMMs and a channel model. Therefore this approach doesn't require any forward error control codes. The proposed approach is applied to correct a code sequence of quantized LSP parameters. Over a noisy channel which is simulated by adding 3% bit errors randomly, it realizes about 39% reduction of cepstrum distortion (16 states HMMs). |
