Abstract :
In this letter, we propose a high resolution time of arrival (TOA) estimation algorithms by using total least square (TLS) based on IEEE 802.15.4a CSS for indoor geolocation. We verify the proposed algorithms through Monte-Carlo simulations in the indoor channel models of IEEE 802.15.4a. The proposed TLS MP can estimate TOA between transceivers more accurately than MP about 0.5 m to 1.7 m at high SNR in CM1.
