Hi,

Why did not everybody answer my question?
This is an emergent question?
I repeat my question again,

1.What is the basic concept of cellphone baseband?
2.How do we design the baseband and audio frequency for cellphone?
Which websites I can find them?

I hope there will have people to answer them,I will appreciate your help.
Thank you!

What do you mean? you mean the Firmware design of the cellphone, IC baseband processor, or other things?
The topic you mentioned is really large. The basic concept of cellphone baseband may contains digital communication, GSM(2G)or 3G protocol.

Good luck

Reading some book on "PCB design on high frequency" may be helpful to you. Just search it in this forum.
