Abstract :
An analysis of time jitter for codes used in synchronous CDMA systems is presented. The system uses a set of either quadratic-residue orthogonal codes or Gold quasi-orthogonal codes. Other user interference power is calculated for both codes taking into consideration the effect of time jitter. The effect of bandlimited chips is also addressed. A modified QR code design which is less sensitive to time jitter is proposed
