Low-Delay 16 kb / s Wideband Speech Coder with Fast Search Methods


In this paper, a low delay 16 kb/s wideband speech coder with a buffering delay of 1.25 ms is introduced. This coder is basically inspired from the G.728 LD-CELP standard for narrowband speech signals. Our main goal is to reduce the implementation complexity of our wideband G728 – like coder, which is mainly due to the search of the optimal excitation (gain… (More)
