Embodiment Construction

[0021] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0022] The calibration method of the present invention first sets the calibration control instance process and the calibration execution instance process for the multi-carrier base station system, wherein the calibration control instance process is the control and command center of the calibration of the present invention, and is responsible for activating the calibration execution instance process and issue the calibration command; while the calibration execution instance process is the specific executor of the calibration command and is responsible for completing the specific calibration task.

[0023] Fig. 1 is the flowchart of calibration method of the present invention, as shown in Fig. 1, calibration method of the present invention comprises:

[0024] Step 101: After receiving the automatic calibration instruction from the multi-carrier base station system, the...

Abstract

Setting up processes of the calibration (CALBR) control and the CALBR execution, the method includes steps: (1) after receiving command of automatic CALBR, the control process parses out ID of object to be calibrated (OTBC) in the command and info of CALBR power; based on info of the ID to activate process of the CALBR execution for OTBC; (2) based on ID of OTBC, the control process determines current power, calculates difference (Diff) between current power and CALBR power, and then determines whether Diff is within the threshold; if yes, returning back finish message; otherwise, entering into (3); (3) based on Diff, the control process determines the gain quantity of CALBR, the gain indication, which are sent to process of the CALBR execution for OTBC; and then the process of the CALBR execution triggers power adjusting for OTBC; after finishing, returning back to (2). Features are: simple, and accomplishing CALBR for all links and carriers by two processes stably and reliably.

Description

technical field [0001] The invention relates to a calibration method in a multi-carrier base station system, in particular to an automatic calibration method based on an instance process in a multi-carrier system. Background technique [0002] Spread spectrum communication has the advantages of anti-interference, anti-multipath, low probability of interception, etc. In recent years, spread spectrum communication has been greatly developed. Spread spectrum communication is at the cost of increasing information transmission bandwidth, and the existing frequency band resources are very limited. In order to increase the rate of information transmission within a unit bandwidth, it is necessary to implement spread spectrum modulation in the link. Spread spectrum modulation is to convert one channel of serial data into multiple channels of parallel data through serial / parallel, and then modulate each channel of data with multiple mutually orthogonal spreading codes to form spread s...
