Abstract :
We introduce both the power and delay capture effect in BER performance analysis of the conventional RAKE receiver for DPSK modulated signals. Depending on the inter-arrival times between the useful and interfering frames from simultaneously transmitting stations, the interference signal noise can be highly correlated or uncorrelated with the DSSS signal from the captured frame.
