Problems solved by technology
[0005] On the one hand, since the guard interval cannot be used to transmit useful signals, the time resources in this interval cannot be fully utilized, resulting in waste of resources and reducing system performance;
[0006] On the other hand, since the receiving end of the signal energy simultaneous interpretation system can only obtain energy from the energy signal, when the receiving end needs an additional energy source in some cases, the system cannot be flexibly configured or provided

The invention discloses a signal energy simultaneous interpretation method and system with a guard interval signal. The method includes steps: S1, the transmitting end generates a controllable guard interval signal according to the current energy demand of the receiving end and the channel transmission environment conditions. The system includes a transmitter for generating a controllable guard interval signal. The invention makes full use of the guard interval time to transmit the guard interval signal with controllable energy size. While preventing inter-symbol interference, it can also provide a controllable energy signal within the guard interval time, improve the energy transmission performance of the system, and reduce the receiving time. Possibility of end not working properly due to lack of energy. The invention can be widely applied to various wireless signal energy simultaneous interpretation systems.
