Title:
CHANNEL CORRECTION METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/219265
Kind Code:
A1
Abstract:
Embodiments of the present invention relate to the technical field of communications and provide a channel correction method and device. The method comprises: obtaining an initial correction coefficient value of a channel; correcting the channel according to the current correction coefficient value, and obtaining a performance parameter value; performing adjustment according to a preset step length if the performance parameter value does not meet a preset stop condition, continuing performing test correction according to the adjusted correction coefficient value to obtain a corresponding performance parameter value, selecting a preferred performance parameter value until the preset stop condition is met, and determining a correction coefficient value corresponding to the preferred performance parameter value; and correcting the channel according to the determined correction coefficient value. By using the system performance as feedback to determine the preferred correction coefficient value, the present invention improves the accuracy of the correction coefficient as well as the system performance. Moreover, the method can be implemented on the basis of processing procedures of a normal service without occupying extra time-frequency resources, and causes no impact on the processing of the normal service.
