Abstract

The 11.8 kb/s extension of the G.729 codec, also known as Annex E of the G.729 Recommendation, has been ratified by the ITU-T. This paper describes how the related test sequences have been designed, using the fixed-point C simulation of the codec. The design method is based on the concept of coverage, already used in the design of test sequences for the G.729 codec. Coverage ensures that all possible parameter values are observed in the bitstream, and all portions of the algorithm are executed at least once. Experiments showed that this approach guarantees a satisfying reliability
