Problems solved by technology

[0002] With the development of communication technology, wireless data transmission has been applied to various devices, such as mobile phones, Internet of Things devices, etc., but there are still technical difficulties in the same-frequency, simultaneous, and full-duplex communication architecture of point-to-multipoint wireless signals. The anti-interference ability of the existing scheme is poor, and a new scheme is urgently needed to solve the above problems
