Detection of CDMA signals

Hello,
I intend to design a simple detector circuit for cdma cell phones. I am intending to base my design on the fact that the modulation scheme for CDMA is fundamentally AM and therefore a simple AM diode detector would serve well.
Is this idea ill advised?

Please aid.

see the link www.google.com/patents where u can find practical circuits

Thanks for the link... I have checked quite a few circuits... I was wondering whether the only thing we need to change in the detectors is the Antenna... for one that is specific to the Country's CDMA spectrum allocation.

hay
why u do not try the fractal antenna especially the adaptive type!!!!!!!!

Thanks. I will factor that into my design consideration
