the main difference is the access method.
CDMA stands for code division multiple access.

hi.... unfortunately i couldnt download those files bcoz i dont have enough points, anyway i wanna ask u what are the hot research topics regaring CDMA? i will be more than happy if u could help me ...........
GSM is 2G mobile technology where TDMA and FDMA is utilized for simultanuous access of different mobile users, while CDMA is mobile communication system which is wideband and in this system each user signal is spread according to a specified code so that signals from each user can be separated at the receiver end.
This is just a basic different,, but there are number of other technical difference too....
