Abstract

The invention relates to a radio frequency system, an antenna switching method and client front-end equipment, and the radio frequency system comprises a receiving module which is used for receiving and processing a radio frequency signal; M antennas, wherein each antenna of the M antennas and the receiving module are connected with the radio frequency transceiver, the M antennas are configured with M ports, and the M antennas are connected with the M ports in a one-to-one correspondence manner through the receiving module to form a preset receiving transmission path of each antenna; configuration information of a preset receiving transmission path is stored in the radio frequency transceiver, the radio frequency transceiver is further used for determining a target transceiving antenna group according to the radio frequency signal received by each port, the target transceiving antenna group comprises N antennas, wherein N is greater than or equal to 2 and less than M. According to theinvention, the insertion loss of a radio frequency front-end circuit in a radio frequency system can be reduced, the sensitivity performance is improved, and the communication performance of the radiofrequency system is further improved.

Description

technical field [0001] The present application relates to the technical field of antennas, in particular to a radio frequency system, an antenna switching method, and customer front-end equipment. Background technique [0002] Customer Premise Equipment (CPE) is a mobile signal access device used to receive mobile signals and forward them with wireless WIFI signals. It is also a device that converts high-speed signals, such as 4G or 5G signals, into WiFi signals. equipment. Generally, multiple antennas are configured in the customer's front-end equipment to support multi-antenna receiving switching. However, in order to realize the multi-antenna switching technology, it is necessary to add multi-level switches in the radio frequency system, the control logic of which is complex, and it will also affect the communication performance of the radio frequency system. Contents of the invention [0003] Embodiments of the present application provide a radio frequency system, an...
