Abstract

Disclosed in the present invention are a DPD loop detection method and device, so as to improve the detection efficiency of the DPD loop. The DPD loop detection method comprises: generating a first test signal, the first test signal being used for detecting at least one performance indictor of a first node device comprised on a DPD loop to be detected, and the first node device being any node device comprised on the DPD loop to be detected; obtaining a value of at least one performance parameter of an output signal of the first node device in the DPD loop to be detected in response to the first test signal; according to the obtained value of the at least one performance parameter, determining whether the at least one performance indicator satisfies a preset condition, the performance parameter being used for measuring the performance indicator; and if it is determined that one performance indicator in the at least one performance indicator does not satisfy the preset condition, commissioning the DPD loop to be detected until the at least one performance indicator satisfies the preset condition.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to a DPD loop detection method and equipment. Background technique [0002] In the modern mobile communication system, the repeater is a supplementary device in the access network of the mobile system, which plays a role in extending the coverage of the base station. As a kind of repeater, digital optical fiber repeater has been widely used due to its advantages of higher output power and longer transmission distance. [0003] At present, in the digital optical fiber repeater system, in order to ensure the linearity of the output signal, a high linear power amplifier is mostly used. However, the work efficiency of the highly linear power amplifier is not high, and the linearity performance improvement is limited. In response to these problems, some digital optical fiber repeater systems apply digital pre-distortion (Digital Pre-Distortion, DPD) technology to improve...
