Have you read the document from rhodes & schwarz? It has some info about all the GSM audio test. Hope this helps a little.

Which of R&S document could you show me ?
The topic question is about acoustic design trouble ,someone have any idea or
web reference about the trouble issue for me .

Hi,

You mean debug the receiver frequency response on hardware or software side?

I am working on a mobile phone which using Skywork platform, the RX freq response can be fine tuned by their software.
