N2 - With 6G technologies taking on new roles in the electrical domain, Orthogonal Time Frequency Space (OTFS) modulation has emerged as a key enabler for integrated sensing and communication. However, parameter estimation in multi-antenna and low-lattice-resolution OTFS (MA-F-OTFS) systems remains underexplored. To address this challenge, this work proposes a hybrid pilot framework based on Chirp structures and Frank sequences, and employs a matrix pencil algorithm to enable efficient joint estimation of multidimensional channel parameters in MA-F-OTFS, including angle, Doppler, and delay. The proposed approach demonstrates fast and accurate estimation performance. The study primarily focuses on Doppler and delay estimation while briefly outlining a joint angle estimation scheme. Simulation results validate the superior performance of the proposed algorithm in parameter estimation.
