Table 2 Multi-pulse excitation coding

From: An efficient solution to sparse linear prediction analysis of speech

Method PESQ SNR
MPE + l2-norm 3.3 9.5 dB
MPE + weighted-l2-norm 3.4 10.2 dB
  1. The quality of Multi-pulse excitation coding using two different synthesizer filters. The multi-pulse excitation source of MPE coder is constructed by taking 10 pulses per 20ms.
