N2 - This paper focuses on the RF index optimization of orthogonal time-frequency space (OTFS). Firstly, an optimization problem is designed to cover the three elements of EVM/DD domain filtering /PAPR. The analysis of this problem shows that an iterative optimization scheme can be designed to solve this problem. Like many traditional researches, the proposed problem can be solved by optimization methods like ADMM. However, traditional methods are opaque and difficult to control which leads to difficulties in deployment, this paper proposes a joint adjustment method of EVM/DD-domain-filtering/PAPR with adjustable joint parameters for practical use, which can adjust the indexes adaptively according to the demand. The simulation results show the system's effectiveness using parameter adjustment to achieve index modification.
