2. A channel with negligible inter-symbol interference (15 3. Rayleigh fading occurs because there is no a non-LOS connection between the source and destination. 4. Pseudo-noise codes are generated in a random fashion. 5. The successfule operation of a RAKE receiver in a DS-CDMA system depends on the chip period being greater than the shortest delay difference between multipath signals.
