A question for cell phone hardware design

[etc]

Hi,

I have a question.
How do we design the baseband circuits for GSM and W-CDMA cell phones.
Could you offer a practical schematic for me,please.How do they work?
Or where can I find those information on Internet?Thank you!

Hello,

Baseband circuits for GSM and WCDMA are very complex ICs which incorporates DSP circuits(modulator, demodulator...), audioprocessing, CPU, memory and so on. Try to take a look to the main baseband manufacturer like TI, NXP, Qualcomm websites if you can gather some very top level block diagram.s

Hope this helps.
