Embodiment Construction

[0038] In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0039] In the prior art, more and more frequency bands are applied to terminals to meet communication requirements. For example, very low frequency (VLF) 3kHz ~ 30kHz applied to ultra-long-distance communications such as coastal submarines; low frequency (LF) 30kHz ~ 300kHz applied to long-distance communications such as transoceanic communications and underground rock formation communications; applied to marine communications and amateu...

Abstract

The embodiment of the invention provides a signal processing system and electronic equipment. The system comprises a first low-noise amplification processor, a first front-end switch module, a plurality of first filters connected in parallel and a radio frequency processor, wherein the plurality of first filters have different filtering frequency bands; the first low-noise amplification processor is used for amplifying the received first signal to obtain a second signal and sending the second signal to the first front-end switch module; the first front-end switch module is used for selecting a target first filter from the plurality of first filters according to the second signal; the target first filter is used for filtering the second signal to obtain a third signal and sending the third signal to the radio frequency processor; and the radio frequency processor is used for processing the third signal. The system can enable a plurality of sub-bands to share one low-noise amplifier, reduces the number of used devices, saves the space of a mainboard, and further reduces the cost and the size of the terminal.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a signal processing system and electronic equipment. Background technique [0002] With the development of terminal technology, the mobile terminal has gradually changed from simply providing communication equipment to a platform for general software operation. The platform no longer provides call management as its main purpose, but provides an operating environment including various application software such as call management, game entertainment, office notes, mobile payment, etc. Every aspect of people's life and work. [0003] Currently, mobile terminals can support more and more communication frequency bands. For example, an LTE (Long Term Evolution, long term evolution) communication signal may include a signal with a frequency between 700 MHz and 2700 MHz. The signals that the mobile terminal can support can be classified into low frequency signals,...
