Embodiment Construction

[0050] The structure of the HF signal acquisition network adopted by the present invention is as figure 2 As shown, the overall network topology is star-shaped, and each peripheral node is configured with a group of half-duplex HF radio stations (TRx: Transceiver) 4 for uploading signals and receiving commands, and the central part is configured with N HF receivers 3 and M HF The transmitter 1 performs centralized signal reception and command delivery, and they work together through the network controller (NCU: Network Control Unit) 2 . Network controller 2 is connected with HF transmitter (Tx: Transmitter) 1 and HF receiver (Rx: Receiver) 3 to control the working status of HF transmitter 1 and HF receiver 3 .

[0051] The uplink design of the present invention is as follows:

[0052] Based on the resource allocation networking strategy, the transmitters, receivers and possible communication frequencies in the central part form the resource pool that the networking system ca...

Abstract

The invention discloses an HF (High Frequency) radio state networking method based on a resource distributing policy. The network is of a star topologic structure which comprises a central part and peripheral nodes. The central part comprises a network controller and a group of HF transmitters and a group of HF receiver, respectively connected with the network controller. The peripheral nodes comprise a half-duplex HF radio station for executing the steps of uploading service data and control signaling of the peripheral nodes and receiving the commands and the control signaling of the central part. The central part is used for receiving centralized service data and control signaling of the peripheral nodes and issuing the commands and the control signaling of the central part. The network controller controls the work state of the HF transmitters and the HF receivers. The transmitter, the receiver and communication frequency possibly used form a resource pond, and uplink and downlink frequencies are selected through uplink and downlink chains. According to the method provided by the invention, the performance is reliable, and the network has good expandability.

Description

technical field [0001] The patent of the present invention relates to the field of wireless communication technology networking, in particular to a resource allocation strategy-based HF radio networking method with limited bandwidth. Background technique [0002] For medium and large-scale HF (High frequency, high frequency) signal acquisition networks, the number U of peripheral nodes will reach hundreds. The general method is to divide the large network into subnets, and then divide the subnets into microgrids. The network topology is as follows: figure 1 shown. [0003] All peripheral nodes are divided into K groups according to their geographical location and communication conditions, and each group has an average of V=U / K peripheral node members. Each group corresponds to a central pair of transmitters and receivers. Each subnet or microgrid forms a point-to-multipoint (P2MP) star network. In this way, frequencies can be planned for different subnets or microgrids. ...
