Multipath Performance Analysis for Navigation Signals in Different Pro-correlation Bandwidth and Correlator Spacing

In this paper,using narrow correlation and double delta correlation techniques,the running average of weighted multipath error envelope of BPSK¹) and BOC¹,1) is simulated in different pre-correlation bandwidth and correlator spacing.The result shows that multipath performance becomes better when correlator spacing decreases,but it's not obvious when correlator spacing is 0.1 chip,and there is a least multipath error when pre-correlation bandwidth increases.
