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!

The topic you mentioned is really large. The basic concept of cellphone baseband may contains digital communication, GSM(2G)or 3G protocol. Good luck
