All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The present invention provides a data optimized transmission method, please refer to fig. 1, where fig. 1 is a flowchart of the data optimized transmission method provided in this embodiment; the method can comprise the following steps:
step s110, determining a transmission signal;
