Abstract :
The effect of signal quantisation on noncoherent matched filter code acquisition in a direct-sequence code division multiple access (CDMA) system is considered. The signal structure is applicable to a wideband CDMA system. The effect of quantisation is derived mathematically and verified using computer simulations with several users. The results indicate that the effect of quantisation is not significant, i.e. from the point of view of acquisition, only a few bits are needed. The effect of signal quantisation can be modelled as a noise increase
