1. A method for reducing a spurious-emission interference, comprising:
determining a target link in wireless communication mode from links in wireless communication mode in a currently operating state, a value of a spurious-emission effect evaluation parameter of the target link in wireless communication mode exceeding a preset range;
performing spurious-emission self-scanning detection on the target link in wireless communication mode, so as to obtain the value of the spurious-emission effect evaluation parameter and a value of the throughput performance evaluation parameter, respectively corresponding to the target link in wireless communication mode when a modulation control parameter has different values;
detecting whether the spurious-emission effect evaluation parameter is an impact factor for a throughput performance evaluation parameter of the target link in wireless communication mode;
determining, when it is detected that the spurious-emission effect evaluation parameter is an impact factor for the throughput performance evaluation parameter, at least one cause factor causing the value of the spurious-emission effect evaluation parameter to exceed the preset range; and
controlling a preset spurious-emission regulation module matching the cause factor to regulate the cause factor, so that the value of the spurious-emission effect evaluation parameter is within the preset range;
wherein the step of detecting whether the spurious-emission effect evaluation parameter is an impact factor for the throughput performance evaluation parameter of the target link in wireless communication mode comprises: detecting, according to a result of the spurious-emission self-scanning detection, whether the spurious-emission effect evaluation parameter is an impact factor for the throughput performance evaluation parameter;
the modulation control parameter comprises a resource block and at least one of a transmission power, an operating band, a bandwidth, an operating frequency and a link coexistence interference;
wherein when it is determined that the cause factor causing the value of the spurious-emission effect evaluation parameter to exceed the preset range comprises a value of a spurious-emission effect evaluation parameter at a target resource block exceeding the preset range, the preset spurious-emission regulation module comprises a spurious-emission filtering and matching module; and
the step of controlling the preset spurious-emission regulation module matching the cause factor to regulate the cause factor comprises: controlling the spurious-emission filtering and matching module to replace, according to the result of the spurious-emission self-scanning result, the target resource block with a new resource block, a value of a spurious-emission effect evaluation parameter of which is within the preset range.
