Sensitivity of MIL-STD-3005 MELP to packet loss on IP networks

The sensitivity of military standard MELP (MIL-STD-3005) to randomly deleted frames on an IP network is studied. Frame deletion occurs when packets are lost or arrive too late to be useful in a voice-over-IP (VoIP) application. Network errors including packet loss, burst loss, jitter and out-of-order packets are simulated. The quality of reconstructed speech is measured by spectral distortion.
