Embodiment Construction

[0032] The following describes the implementation of the present invention in detail with reference to the accompanying drawings. The examples given are for illustrative purposes only and should not be understood as limiting the present invention. The accompanying drawings are for reference and illustrative purposes only, and do not constitute the scope of patent protection of the present invention. Limitation, because many changes can be made to the present invention without departing from the spirit and scope of the present invention.

[0033] The transmit power is mainly controlled by the baseband TX gain parameters, RF gain, and PA gain parameters. In this embodiment, the power range is calibrated in sections considering the margin, and the RF gain is set in sections to calibrate the baseband TX gain parameters. The power varies with the baseband TX gain parameters. Increase and increase (TX is the abbreviation of transport, meaning transmission). Based on this, such as figur...

Abstract

The invention relates to the technical field of NB-IOT, and particularly discloses a transmitting power point calibration method for NB-IOT equipment and a storage medium. The method comprises the steps of firstly, giving the same value to the same power section to a conventionally calibrated RF gain parameter-power oscillogram; adjusting the conventionally calibrated TX gain parameter-power oscillogram according to the processed RF gain parameter-power oscillogram, therefore, the voltage of each power section can be approximately expressed by a quadratic function; calculating an expression ofa quadratic function of each power section by selecting three power points for calibration in each section; and finally, substituting a specific power point into the corresponding quadratic functionexpression to obtain a corresponding baseband TX gain parameter value. The baseband TX gain parameter values of all the power points can be obtained only by calibrating not more than one third of thepower points. The calibration time is greatly reduced. The calibration efficiency is improved. The error is controlled within a receivable range, and the calibration quality is ensured.

Description

Technical field [0001] The present invention relates to the field of NB-IOT technology, and in particular to a method and storage medium for calibration of transmit power points of NB-IOT equipment. Background technique [0002] Narrowband Internet of Things (NB-IoT) is widely used in low-power products. With the growth of market demand, production efficiency and cost have become important issues. In the production calibration process, reducing calibration time and improving calibration efficiency can effectively improve production efficiency And reduce long-term production costs. [0003] The current conventional transmit power calibration ranges from -45dBm to 24dBm, with a step of 1dBm, and a total of 70 power points. If each power point is calibrated, it will take up most of the calibration time. Summary of the invention [0004] The present invention provides a calibration method and storage medium for transmitting power points of NB-IOT equipment. The technical problem to be ...
