Embodiment Construction

[0085] see Figure 5 As shown, since the vicinity of point "A" is the peak value of the shock envelope amplitude during the entire signal transition process, it is not only the most reliable to transmit effective data near this point, but also does not need to wait for the end of the shock filter transition process of the receiver, so it is also faster . For example, in Figure 5 In the middle, although the envelope amplitude of the signal is stable at about 14 after passing the "D" point, the envelope amplitude of the signal is not lower than 20 between the "E" point and the "F" point. The signal power ratio of (20 / 14) 2 ≈2, which is equivalent to at least doubling the signal transmission power (or at least half the signal transmission power), the power efficiency is greatly improved, and the energy saving effect is remarkable. And it can save at least half of the transmitter work and channel occupation time than starting valid data at point "C".

Description

technical field [0001] The invention belongs to the technical field of digital communication and wireless sensor network, and in particular relates to an extremely high-speed burst communication method for transmitting short data or small data packets by using the transient peak energy of a received signal in the establishment process. Background technique [0002] 1. Sensor network and burst communication [0003] Wireless Sensor Network (WSN: Wireless Sensor Network) is an important support of the Internet of Things. It is usually a multi-hop data communication network composed of a large number of spatially distributed automatic devices in a self-organizing form, so as to transmit monitoring data to the receiving center for processing. . In addition to one or more sensors, WSN nodes are also equipped with radio transceivers and microcontrollers. The size and cost depend on the scale of WSN and the complexity of a single sensor node. Usually this kind of WSN node is powe...
