A 1 . 6 Kb / S Melp Coder for Wireless Communications

  title={A 1 . 6 Kb / S Melp Coder for Wireless Communications},
  author={McCree and Juan Carlos De Martin},
This paper describes our new Mixed Excitation Linear Predictive (MELP) coder designed for wireless applications. This new coder, through algorithmic improvements and enhanced quantization techniques, produces better speech quality at 1.6 kb/s than the new U.S. Federal Standard MELP coder at 2.4 kbls. A key feature of the coder is a novel Line Spectral Frequencies (LSF) quantization scheme, requiring only 20 bits per frame. With channel coding, the new MELP coder at 3.1 kbls is capable of… CONTINUE READING
