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] Such as 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...

Abstract

The invention discloses a transmission channel power adaptive method, an adaptive device, and a sending device. The method includes adjusting the transmission channel power when the sending device is in the first working state, so that the E of the receiving device s / N 0 Satisfy the theoretical demodulation threshold; when the sending device switches to the second working state, according to the adjusted transmission channel power in the first working state, the working parameters of the sending device in the first working state, and the parameters of the sending device in the second working state Working parameters, and the theoretical demodulation threshold E of the receiving device in the first working state s / N 0 and the theoretical demodulation threshold E of the receiving device in the second working state s / N 0 , calculating actual transmit channel power when the sending device is in the second working state, and configuring the actual transmit channel power for the sending device in the second working state. When guaranteeing the link quality, the transmission power should be reduced as much as possible to reduce the interference of adjacent channels and the burden of satellite transponders and power amplifiers.

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...
