Problems solved by technology

[0002] In the existing satellite communication network, there are strict requirements on the power control of the transmission channel. If the transmission power is too large, it may cause adjacent channel interference and increase the burden on the RF power amplifier. If the transmission power is too low, it will lead to poor link quality. , or even broken chain

Embodiment Construction

[0025] like figure 1 As shown in FIG. 2 , it is a schematic diagram of a working network structure of devices in an embodiment of the transmission channel power adaptive method of the present invention.

[0026] Device 1 is the sending device and Device 2 is the receiving device. Device 1 transmits a signal, which is received by Device 2 via the satellite network.

[0027] When the device, the power amplifier, and the antenna are determined, the device 1 is in the reference working state or the first working state.

[0028] Specifically, the working parameters of the device 1 in the first working state include the first symbol rate SymbolRate ref , the first frame type BurstsMode ref , the first modulation code rate ModeCode ref , or respectively called the reference symbol rate SymbolRate ref , reference frame type BurstsMode ref , Reference modulation code rate ModeCode ref .

[0029] Adaptive step 1, preset: adjust the transmission channel power when the device 1 is...

Abstract

The invention discloses a transmitting channel power self-adaption method, a transmitting channel power self-adaption device and a transmitting device, and the method comprises the steps: adjusting the transmitting channel power of transmitting equipment in a first working state, so as to enable ES/N0 of receiving equipment to meet a theoretical demodulation threshold; when the transmitting equipment is switched to a second working state, according to the adjusted transmitting channel power in the first working state, the working parameters of the transmitting device in the first working stateand the working parameters of the transmitting device in the second working state, and a theoretical demodulation threshold Es/N0 of the receiving device in the first working state and a theoreticaldemodulation threshold Es/N0 of the receiving device in the second working state, calculating actual transmitting channel power when the transmitting equipment is in the second working state, and configuring the actual transmitting channel power for the transmitting equipment in the second working state. When the link quality is ensured, the transmitting power is reduced as much as possible, and the adjacent channel interference, satellite transponder and power amplifier burdens are reduced.

Description

technical field [0001] The invention relates to satellite communication technology, in particular to a transmission channel power self-adaptation method, an self-adaptation device and a transmission device. Background technique [0002] In the existing satellite communication network, there are strict requirements on the power control of the transmission channel. If the transmission power is too large, it may cause adjacent channel interference and increase the burden on the RF power amplifier. If the transmission power is too low, it will lead to poor link quality. , or even break the chain. Therefore, it is particularly important to precisely control the transmission channel power. Contents of the invention [0003] In order to solve the deficiencies in the related prior art, the present invention provides a transmit channel power adaptive method, an adaptive device, and a sending device. Parameters such as modulation code rate, frame type, and symbol rate can more acc...
