Cdma uses a 64-ary modulator:

Code-division multiple access (CDMA) is a channel access method used by various radio communication technologies. CDMA is an example of multiple access, where several transmitters can send information simultaneously over a single communication channel. This allows several users to share a band of frequencies (see bandwidth). To permit this without undue interference betwee… WebCDMA is a Spread-Spectrum System. Traditional Technologies try to. squeeze signal into minimum. required bandwidth. CDMA uses larger Bandwidth but. uses resulting processing gain to. increase capacity. CDMA (Code Division Multiple Access) Different Stations use the entire frequency band at same time.
