Abstract :
At a certain type of weapons training simulator of the audio transmission system, the decoder of AMR-WB+ on FPGA platform is realized based on the system framework of AMR-WB+ algorithm. Firstly, FPGA developing status and related technologies are introduced subsequently, together with the usage of the EDK Development Kit. And the paper gives the basic principle of AMR-WB+ codec, introduces the basic structure of decoder, and presents the basic model of mono signal codec. Afterwards, the achievable steps of running and debugging the AMR-WB+ decoding algorithm on the PC platform are presented. The porting procedure of ANSI C from PC to FPGA platform are introduced. Finally, the problems and solutions during the debugging are given.
