Abstract :
A cyclostationarity-based time difference of arrival (TDOA) estimation algorithm is proposed for modulated signals in multipath environments. The performance of the algorithm based on cyclostationarity is evaluated by simulation for a BPSK signal and compared with the cumulant-based algorithm. The simulation shows the proposed algorithm outperforms the cumulant-based algorithm, especially for cyclostationary interferences in multipath environments.
