Non-voice performance of the 16 kbit/s LD-CELP algorithm

Abstract Recently, CCM adopted a Low-Delay Code Excited Linear Predictive (LD-CELP) algorithm as a new recommendation for the coding of telephone bandwidth speech at 16 kbit/s with “toll quality”. In this paper, the performance of the LD-CELP algorithm with non-voice signals is presented and compared with 64 kbit/s PCM. From these results it can be determined that the LD-CELP, in a single encoding/decoding configuration. is acceptably transparent to network signaling as well as voiceband data at rates not exceeding 2.4 kbit/s.
