BA–POC-Based Ranging Method With Multipath Mitigation

Binary asymmetric–phase-only correlation (BA–POC) is investigated in this letter, and for the first time is applied into the area of ranging to help identify the line-of-sight (LOS) signal in multipath-abundant environments. Measurements made based on the 2.45-GHz wireless signal indicate that BA–POC has superior performance in mitigating multipath signals when compared with the conventional correlation method, and thus is able to increase the ranging accuracy.
