This paper considers Global Navigation Satellite System (GNSS) receiver signal processing-based methods for mitigating multipath using novel correlator waveform concepts. The "Gated Correlator" approach utilizes blanking of the received signal between code chip transitions. Applying the Gated Correlator to GPS C/A-code yields code and carrier multipath mitigation performance that surpasses conventional GPS P-code performance. The "High Resolution Correlator" technique approximates the performance of the Gated Correlator but can be obtained using multiple correlator outputs from conventional receiver hardware. The multipath performance of these methods is similar to the performance claimed for other methods reported in the literature. However here a complete derivation for these methods is presented as well as a detailed assessment of the performance of these techniques in the presence of wideband noise.
