Abstract :
The effect of clock jitter on sampling systems is presented. Analytical expressions are derived for the signal-to-noise ratio using the autocorrelation function and its properties. Special focus is given to direct sampling systems for signals with raised cosine power spectral density. Phase noise requirements in CDMA systems are calculated with respect to SNR.
