However, the asynchronicity between transmitters and receivers results in velocity and range ambiguity, which seriously degrades the sensing performance. To mitigate the ambiguity, carrier frequency offset (CFO) and time offset (TO) synchronizations have been studied in the literature. However, their performance can be significantly affected by the specific choice of the window functions harnessed. Hence, we set out to find superior window functions capable of improving the performance of CFO and TO estimation algorithms. We firstly derive a near-optimal window, and the theoretical synchronization mean square error (MSE) when utilizing this window. However, since this window is not practically achievable, we then test a practical \"window function\" by utilizing the multiple signal classification (MUSIC) algorithm, which may lead to excellent synchronization performance.","16 pages, 12 figures, accepted to publish on IEEE Transactions on Communications, Aug. 2024"],"publicationDate":"2025-02-01","publisher":"Institute of Electrical and
