Selective discarding procedure for improved tolerance to missing voice packets
M.M. Lara-Barron, G.B. Lockhart · Electronics Letters · 1989
A selective packet discarding procedure for voice communication is presented in which packets are labelled at the transmitter and, if necessary, discarded by network nodes according to their significance to reconstructed speech quality. Simulation and subjective tests show improved tolerance to missing packets in comparison with unselective methods where packets are discarded at random.
