Problems solved by technology

When there is no master control node in the communication network, if there is competition and information transmission error occurs, it can only be solved by error retransmission, which will lead to a decrease in effective bandwidth. If the number of nodes in the communication network is large, the probability of competition conflict will increase, resulting in a significant decrease in system bandwidth

Embodiment 1

[0070] There are two communication terminals in the system, namely terminal A and terminal B. The schematic diagram of time slot allocation in the system is as follows: image 3 shown. The mutual communication between terminal A and terminal B is completed through the following steps:

[0071] 1) Initialize system parameters: the frame synchronization sequence is PN sequence; the second pulse period is 1 second; the signal frame period is 1 / 4 of the second pulse, that is, 0.25 seconds; the total number of time slots is 2; the transmission time slot of terminal A is Slot 1, the receiving time slot is time slot 2; the transmitting time slot of terminal B is time slot 2, and the receiving time slot is time slot 1;

[0072] 2) Perform satellite timing synchronization. After the satellite timing synchronization is completed, a second pulse signal is generated, and the second pulse signal period is 1 second; and according to the signal frame period, the satellite second pulse signa...

Abstract

The invention discloses a satellite timing service-based wireless communication method and a satellite timing service-based wireless communication device, for realizing multi-point ordered communication without a master control node or a base station signal. The method disclosed by the embodiment of the invention comprises the following steps of: initializing system parameters; carrying out satellite timing service synchronization and generating a pulse-per-second signal and a satellite frame pulse signal; carrying out frame synchronization sequence detection to generate a detection frame pulse signal; correcting the frame pulse signal according to the satellite frame pulse signal and the detection frame pulse signal; carrying out time slot configuration; carrying out coding, modulation and insertion for a frame synchronization sequence in a transmission time slot, carrying out modulation and decoding in a reception time slot, and switching into a transmitting state or a receiving state according to whether service data needs to be sent.

Description

technical field [0001] The present invention relates to a wireless communication technology, in particular to a wireless communication method and device based on satellite timing. Background technique [0002] Wireless communication The development history can be traced back to the 19th century. 1864 Maxwell Theoretically proved the existence of electromagnetic waves; in 1876 Hertz confirmed the existence of electromagnetic waves experimentally; in 1900 Marconi et al. using electromagnetic waves for long-distance radio The communication was successful, and the world entered radio communication new era. [0003] The Beidou satellite navigation system is a global satellite navigation system independently developed and operated independently by China. GPS , Russia The GLONASS and the EU's Galileo systems are compatible with the shared global satellite navigation system, and are called the world's four major satellite navigation systems. Both Beidou satellite navig...
