Title:
BASEBAND RADIO FREQUENCY INTERFACE, COMMUNICATION SYSTEM, AND SIGNAL RECEIVING METHOD
Document Type and Number:
WIPO Patent Application WO/2021/134493
Kind Code:
A1
Abstract:
The present application provides a signal receiving method and apparatus, and a baseband radio frequency (BB-RF) interface. The BB-RF interface comprises a physical layer processing circuit, a synchronization state machine coupled to the physical layer processing circuit, and a first protocol state machine and a second protocol state machine that are separately coupled to the synchronization state machine; the physical layer processing circuit is used for receiving a serial bit stream, and according to the serial bit stream, generating parallel data; the synchronization state machine is used for selectively transmitting the parallel data to the first protocol state machine or the second protocol state machine for processing; and a first BB-RF communication protocol supported by the first protocol state machine is different from a second BB-RF communication protocol supported by the second protocol state machine. When a network device uses the BB-RF interface provided by the present invention, the compatibility of the network device can be improved, and the manufacturing cost can be significantly reduced.
