At the end of the introduction, I will explain the final goal of this research.
The purpose of this research is to propose a method that enables sufficient SI cancellation without using RF canceling, which is difficult to implement, and to demonstrate it with an actual machine.
In the demonstration using an actual machine, it is necessary to examine the SI cancellation performance of the proposed method, and the interference signal to noise ratio (INR) before applying digital canceling is used as an index.
If the INR is 50 [dB] or less, the self-interference signal remaining after applying the proposed method can be sufficiently canceled by using digital canceling.
Therefore, the ultimate goal of this research is to propose a method that can achieve INR 50 [dB] or less and prove it by actual machine experiments. |
