Performance Analysis of BEM-based Channel Estimation for OTFS with Hardware Impairments
Haowei Wu, Huanyu Chen, Qihao Peng +2
This letter studies the low-complexity channel estimation for orthogonal time frequency space (OTFS) in the presence of hardware impairments. Firstly, to tackle the computational c…
