Embodiment Construction

[0033] In the following description, specific details such as specific system structures and technologies are presented for the purpose of illustration rather than limitation, so as to thoroughly understand the embodiments of the present application. It will be apparent, however, to one skilled in the art that the present application may be practiced in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present application with unnecessary detail.

[0034] Usually, in order to make full use of the limited bandwidth resources of a live broadcast satellite, the transponder will send two beams at the same time, and the vertical transmission between the two beams will not interfere with each other. The vertical transmission mode can be divided into linear polarization (vertical and horizontal transmission) and circular polarization ...

Abstract

The embodiment of the invention is suitable for the technical field of signal processing, and provides a low-noise down converter, a signal processing method and a storage medium, and the low-noise down converter comprises: a first feed source which is used for receiving a first satellite signal transmitted by a first satellite; a first local oscillator unit electrically connected with the first feed source and used for mixing the first satellite signal to obtain a first intermediate frequency signal belonging to a preset first frequency band; a second feed source and the first feed source areindependently configured, wherein the second feed source is used for receiving a second satellite signal emitted by a second satellite; and a second local oscillator unit which is electrically connected with the second feed source and is used for mixing the second satellite signal to obtain a second intermediate frequency signal belonging to a preset second frequency band, wherein the first frequency band and the second frequency band are not overlapped with each other. According to the low-noise down converter, multiple feed sources can work at the same time and do not interfere with one another.

Description

[0001] This application declares that it enjoys the priority of the Chinese invention patent application with the application date of December 27, 2019, the application number 201911374995.7, and the title of "a low-noise down-converter, signal processing method and storage medium". technical field [0002] The application belongs to the technical field of signal processing, and in particular relates to a low-noise down-converter, a signal processing method and a storage medium. Background technique [0003] Low Noise Down Converter (Low Noise Block, LNB) is the high frequency head, its function is to amplify and down convert the satellite signal transmitted by the feed source, and convert the high frequency signal to the intermediate frequency, so as to facilitate the transmission of coaxial cable and satellite Demodulation and operation of the receiver. [0004] Typically, an LNB with two feeds will only work with one of the two feeds when receiving satellite signals. If ...
