Next, we will introduce the OMP channel estimation algorithm. The key of the pilot-based channel estimation for OTFS communication system is the placement design of pilot symbol and data symbols. Since the DD domain channel can obtain the full TF diversity gain, we use the traditional pilot scheme to obtain the full channel response. The DD domain signal after inserting the pilot symbol can be written as formula (10). |
