Next, the advantages and issues of the proposed method will be explained.
The major advantages of the proposed method are that sufficient self-interference cancellation can be achieved without using an RF canceller, which is difficult to implement, and that the proposed method can be applied without significantly changing the existing wireless communication standard. Compared to the self-interference canceling method using normal spatial canceling, the reduction rate of the degree of freedom is small.
On the other hand, as an issue, since Co-MIMO is applied to the proposed method, it is essential to synchronize the clocks between APs and the transmission timing. |
