MPE/LTP speech coder for mobile radio application

Abstract In this paper, we describe our contribution to the CEPT effort for the definition of a European standard for the cellular mobile radio. We first give an overview of the Multipulse excitation with long term prediction (MPE/LTP) algorithm. Then, we report details on the implementation (constants, quantizing tables) respectively in the analysis part, the error protection/correction, and the synthesis part of the codec. Finally, we report detailed figures about the implementation efficiency (ROM/RAM/Cycles).
