Embodiment Construction
[0139] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments . Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0140] As mentioned above, in the existing technologies for improving the wireless transmission rate of BLE, reducing the symbol period of Gaussian Frequency Shift Keying (GFSK: Gaussian Frequency Shift Keying) modulation is greatly affected by multipath interference, and the performance of long-distance transmission is poor. Differential phase shift keying (DPSK: Differential Phase Shift Keying) or multi-carrier modulated m...
