The present invention provides a method and device, system, storage medium and electronic device for determining a reference clock. The above method includes: performing the following operations on each remote machine in the target loop, and performing the following operations on each remote machine In operation, each remote machine is determined as the current remote machine: obtain the first signal received by the first port of the current remote machine from the target ring, and the second port of the current remote machine received from the target ring The second signal received; according to the first signal and the second signal, determine that one of the first port and the second port of the current remote machine is a slave port, and the other port in the first port and the second port is Master port; determine the reference clock of the current remote machine according to the signal received by the slave port of the current remote machine from the target loop. The invention solves the technical problem that the phase noise of the reference clock of the remote equipment in the loop increases due to the increase in the number of cascading stages of the remote equipment in the loop.
Description
technical field [0001] The present invention relates to the communication field, in particular, to a method and device, system, storage medium and electronic device for determining a reference clock. Background technique [0002] The distributed coverage system includes equipment such as base stations, near-end units (also called access units, Access Unit, AU for short), remote units (also called remote units, Remote Units, RU for short), and each Each device includes a transmitter, a receiver, and a digital pre-distortion (Digital Pre-Distortion, DPD for short) feedback path. Various transmitters and receivers can include data converters such as Analog to Digital / Digital to Analog Converters (ADC / DAC for short), because the phase noise and jitter performance of the clock generator will affect the data The dynamic range and linearity performance of the converter have a serious impact, which in turn affects the transmit / receive error vector magnitude (Error Vector Magnitude,...
