Multipath Invariance Approach Code Multipath Mitigation
2015/6/29
The concept of multipath invariance asserts that there exist properties and/or regions of the code correlation function that do not change as a function of the multipath amplitude, delay, phase and ph...
Narrowband receivers are more robust to narrowband interference and to GPS signal faults, but they tend to have relatively poor multipath performance. Few current techniques are capable of mitigating ...
