Wideband Test and Evaluation.

Abstract

The performance of seven wideband (16 kb/s or greater) coders was tested and evaluated for comparison of recently developed speech coders with speech coders based on the continuously variable slope delta (CVSD) algorithm. The CVSD coder at 32 kb/s was superior to the other coders at 16 kb/s. Under nontactical conditions on some tests the APCQ speech coder was superior to the CVSD at 32 kb/s. Under tactical conditons the CVSD coder was superior to other 16 kb/s speech coders. (Author)
