Networking initialization method of single-frequency transfer digital wireless communication system

Abstract

The invention provides a networking initialization method of a single-frequency transfer digital wireless communication system. The networking initialization method of the single-frequency transfer digital wireless communication system comprises the following steps: S1, in networking equipment, selecting one equipment as a central link machine which is responsible for the core work of the whole networking process, and initializing related information and flag bits for the central link machine and a non-central link machine; all the non-central link machines are powered on, initially set at dual time slots of a common frequency F0 and start to monitor information, and then a networking step is started; and S2, after the non-central link machine initially receives the beacon packet, extracting related information in the beacon packet, after receiving a network access response packet sent back by the central machine, changing a flag bit in the system into a network access state, and sending a beacon packet constructed by the non-central link machine in a next time slot, and after receiving the beacon packet, a secondary link machine sends the beacon packet in the next time slot. According to the invention, the networking process among a plurality of transfer stations is realized, and the expansion of the communication range is realized.

Description

technical field [0001] The invention relates to the technical field of wireless communication technology, in particular to a network initialization method of a single-frequency relay digital wireless communication system. Background technique [0002] In wireless communication, the communication range of a single terminal is very limited, and the communication range can be increased by adding relay devices to forward and enhance signals. [0003] The relay equipment is based on the DMR communication protocol, adopts the TDMA method, and works independently with single frequency and double time slots. When the number of relay stations increases, the division of communication channel frequencies is more complicated, and it is difficult to use the relay station to expand the communication range. [0004] Therefore, it is urgent to redesign a new network initialization method of a single-frequency transit digital wireless communication system to solve the above-mentioned problem...
