A satellite test signal generation method, device, electronic equipment and storage medium

Abstract

The embodiment of the invention provides a satellite testing signal generation method and device, electronic equipment and a storage medium. The method comprises the following steps that: generating apseudorandom sequence with a preset length and a preset chip rate; carrying out constellation diagram mapping on the pseudorandom sequence to obtain a first complex number value; taking preset sampling frequency to carry out equal-time-interval oversampling on the complex number value to obtain a plurality of second complex number values; taking the second complex number values as sampling points, and storing the sampling points by a first preset format of file; and converting the first preset format of file into a second preset format of file so as to enable a satellite signal generator to generate a satellite testing signal by the second preset format of file. By use of the satellite testing signal generation method and device of the embodiment of the invention, various testing requirements of testing personnel on the satellite testing signal can be met.

Description

technical field [0001] The invention relates to the technical field of satellite communication, in particular to a satellite test signal generation method, device, electronic equipment and storage medium. Background technique [0002] In the field of satellite communication, it is necessary to test and analyze satellite signals. For example, testers can generate satellite test signals through satellite signal generators, and then perform satellite mobile fading channel modeling on the generated satellite test signals, so as to test and analyze satellite mobile signals. Multipath Effects for Fading Channel Models. [0003] Among them, the multipath effect means that after the electromagnetic wave propagates through different paths, each component field arrives at the receiving end at different times, and superimposed on each other according to their respective phases to cause interference, distorting the original signal, or generating errors. When analyzing the quality of a ...

Problems solved by technology

[0004] However, the inventor found in the process of realizing the present invention that at least the following problems exist in the prior art: the existing satellite signal generation method usually relies on the parameters carried by the satellite signal generator itself to generate the satellite test signal, and the satellite signal generator generally Composed of hardware such as a radio frequency signal generator, the existing satellite signal generator itself has limited modifiable parameters in the signal waveform, which makes it difficult for the generated satellite test signal to meet various test requirements, for example, it is difficult to meet the requirements of satellite channel construction. The test requirements for multipath effects in the model are especially difficult to meet the test requirements for the measurement accuracy of multipath delay extension in the satellite mobile fading channel model
