Cause at carrying out unidirectional, single-point calibration by continuous wave in the correlation technique that calibration efficiency is low, the calibration process complicated problems, the present invention proposes, by allow terminal and instrument realize based on descending synchronous signal channel (DwPTD) synchronously, and utilize the available time slot of TD-SCDMA frame to calibrate, not only can realize the executed in parallel of up calibration and descending calibration, and calibration when can realize a plurality of calibration item, thereby effectively improve the efficient of calibration, reduce the complexity of calibration process.
Below in conjunction with accompanying drawing, describe embodiments of the invention in detail.
According to embodiments of the invention, a kind of implementation method of terminal calibration is provided, be used to the calibration that realizes that instrument is right.
Before detecting, at first main frame, instrument and terminal can be connected according to mode shown in Figure 2, wherein, main frame can be to have the equipment (also can be described as host computer) that terminal and instrument are controlled, for example, can be computer, instrument can be any calibrator (-ter) unit (for example, can be comprehensive tester) that possesses the function that terminal is calibrated.As shown in Figure 2, can be connected by GPIB line (GBIP Cable) between main frame and the instrument, can be connected by USB or UART interface between main frame and the terminal, can be connected by RF line (RF Cable) between terminal and the instrument, connected mode between each equipment shown in Figure 2 only is concrete example, can main frame, terminal and instrument be connected by other modes in actual applications.
As shown in Figure 1, the implementation method of calibrating according to the terminal of the embodiment of the invention comprises:
Step S101, instrument receives descending synchronous signal channel parameter and the calibration parameter from main frame, and wherein, calibration parameter is used to indicate the transmission means of calibration data;
Step S103, instrument utilizes descending synchronous signal channel to send synchrodata to terminal, and wherein, descending synchronous signal channel is obtained according to the descending synchronous signal channel parameter configuration by instrument;
Step S105, thereby terminal is by detecting synchrodata with instrument and after finishing synchronously, instrument sends descending calibration data by TD SDMA TD-SCDMA Frame to terminal and also receives the up calibration data of self terminal according to calibration parameter, thereby finishes the calibration to terminal.
By means of above-mentioned processing, by allow terminal and instrument realize based on descending synchronous signal channel (DwPTD) synchronously, and utilize the available time slot of TD-SCDMA frame to calibrate, not only can realize the executed in parallel of up calibration and descending calibration, and can when realizing a plurality of calibration items, calibrate the different time-gap of TD-SCDMA Frame, thereby effectively improve the efficient of calibration, reduce the complexity of calibration process.
Wherein, main frame also should be prenoticed to terminal except the descending synchronous signal channel parameter being notified to the instrument, and instrument and terminal are finished synchronously and be meant: terminal successfully detects descending synchronous signal channel according to the descending synchronous signal channel parameter from main frame.Preferably, in order simply to conclusively show descending synchronous signal channel, the descending synchronous signal channel parameter can comprise following one of at least: the frequency of descending synchronous signal channel, the power of descending synchronous signal channel.
In addition, calibration parameter can comprise up calibration parameter and descending calibration parameter, and calibration parameter should be prenoticed to terminal by main frame equally, wherein, descending calibration parameter is used for the transmission means of indicating downlink calibration data, up calibration parameter is used to indicate the transmission means of up calibration data, makes terminal and instrument all can obtain up calibration parameter and descending calibration parameter.
Alternatively, main frame can be notified to terminal with calibration parameter and descending synchronous signal channel parameter earlier, and after notify instrument with above-mentioned parameter, and inform that instrument is ready for sending synchrodata.
Based on this, when terminal sends descending calibration data, can send descending calibration data by the TD-SCDMA Frame to terminal according to descending calibration parameter in instrument; When instrument receives the up calibration data of self terminal, can be according to the up calibration data of up calibration parameter receiving terminal by the transmission of TD-SCDMA Frame.
Correspondingly, terminal also needs to send up calibration data by the TD-SCDMA Frame to instrument according to up calibration parameter; And terminal also needs according to descending calibration parameter, and receiving instrument so just can be realized the mutual of calibration data by the descending calibration data that the TD-SCDMA Frame sends.
Because a TD-SCDMA Frame comprises ascending time slot and descending time slot, therefore,, should indicate the time slot, control word and/or the frequency that are used to transmit calibration data in the calibration parameter in order clearly to indicate how to transmit calibration data.For example, descending calibration parameter should indicate the shared time slot of descending calibration data, frequency and control word, and up calibration parameter should indicate the shared time slot of up calibration data, frequency and control corresponding word.By clearly indication to up calibration data and the shared time slot of descending calibration data, just can make full use of all available time slot of TD-SCDMA Frame, be used to transmit calibration data, therefore, in a TD-SCDMA Frame, the calibration of a plurality of calibration items can be carried out, the efficient of calibration can be effectively improved.
Alternatively, in order to guarantee that calibration can rationally be triggered, before carrying out synchronously, main frame can be further with a frequency threshold value (for example, can called after T) be notified to terminal and instrument, can under following two kinds of situations, start the transmission of calibration data like this:
(mode one) terminal and instrument send calibration data to the other side simultaneously under the situation that successful synchronous condition satisfies, wherein, success synchronous condition is meant: instrument and terminal are finished synchronously and instrument reaches predetermined value to the frame number that terminal sends synchrodata, that is to say, instrument can send synchrodata at the descending synchronous signal channel of each Frame, finish synchronously if the frame number that sends reaches T and terminal and instrument, then both sides send calibration data simultaneously mutually;
(mode two) instrument response sends descending calibration data in the up calibration data that comes self terminal to terminal, and wherein, terminal sends up calibration data to instrument immediately after finishing synchronously.Similarly, under this mode, can utilize this T value to judge equally, that is, send in the process of synchrodata at the descending synchronous signal channel of instrument by Frame, if the frame number that sends reaches T, and terminal and instrument remain unfulfilled synchronously, then think synchronization failure.
In addition, alternatively, can also be set a lock in time, substitute above-mentioned frequency threshold value T, thereby carry out according to the time span of carrying out synchronously whether successful judgement or triggering calibrated synchronously, its process and said process are similar, no longer repeat here.
To be described in detail concrete processing procedure of the present invention below.
As shown in Figure 3, one is example in the above described manner, specifically may further comprise the steps:
Step 31, main frame (PC) at first notify terminal to be measured to prepare the synchrodata that receiving instrument sends, simultaneously with synchronous count parameter (that is, above-mentioned frequency threshold value) T, descending synchronous signal channel (DwPTD) parameter and calibration parameter notice terminal; Wherein, count parameter T can for example, can be set to 25～50 subframes according to each terminal synchronizes capabilities setting synchronously, and calibration parameter comprises frequency, control word and the time slot of up-downgoing calibration; The descending synchronous signal channel parameter comprises the frequency and the power grade of descending synchronous signal channel.
Step 32, the host notification instrument is ready for sending synchrodata, simultaneously with synchronous count parameter T, descending synchronous signal channel (DwPTD) parameter and calibration parameter notice instrument;
Step 33, instrument is according to descending synchronous signal channel parameter configuration descending synchronous signal channel, and beginning sends synchrodata in the synchronizing channel of every frame, when sending the first frame synchronization data, instrument coincidence counter TDync counting is 1, and after this counter adds up by the sub-frame number that sends;
Step 34: terminal detects descending synchronous signal channel, and does synchronous detecting and adjustment according to detected descending synchronous signal channel;
Step 35: if synchronization failure between terminal and the instrument, then terminal is notified to main frame with synchronization failure; And execution in step 36;
Step 36, main frame is notified to instrument with synchronization failure, finishes this calibration;
If success synchronously between terminal and the instrument, then after step 34, direct execution in step 37;
Step 37, instrument and terminal begin to carry out the up-downgoing calibration according to the TD-SCDMA frame structure.
Preferably, in above-mentioned steps 33, when instrument begins to send synchrodata, should guarantee that terminal has entered the synchrodata accepting state, otherwise after instrument sends data, terminal can not in time receive data, cause the omission of synchrodata, and the coincidence counter of instrument and terminal can't align.
In step 35,36, if adopt aforesaid way one, then the terminal synchronous count parameter T that equals to dispose at success synchronously and coincidence counter is (because there are relation in the length of Frame and time, therefore, terminal can be known the pairing duration of frame number T) time, beginning sends up calibration data at the ascending time slot of configuration (determining according to up calibration parameter), and receives descending calibration data simultaneously; Instrument begins the up calibration data of receiving terminal when the synchronous count parameter that coincidence counter equals to dispose, and sends descending calibration data at the time slot of stipulating simultaneously;
As shown in Figure 4, two is example in the above described manner, specifically may further comprise the steps:
Step 41, main frame at first notify terminal to be measured to prepare the synchrodata that receiving instrument sends, simultaneously with synchronous count parameter (that is, above-mentioned frequency threshold value) T, descending synchronous signal channel (DwPTD) parameter and calibration parameter notice terminal; Wherein, count parameter T can be according to each terminal synchronizes capabilities setting synchronously, and calibration parameter comprises frequency, control word and the time slot of up-downgoing calibration; The descending synchronous signal channel parameter comprises the frequency and the power grade of descending synchronous signal channel.
Step 42, the host notification instrument is ready for sending synchrodata, simultaneously with synchronous count parameter T, descending synchronous signal channel (DwPTD) parameter and calibration parameter notice instrument;
Step 43, instrument is according to descending synchronous signal channel parameter configuration descending synchronous signal channel, and beginning sends synchrodata in the synchronizing channel of every frame, when sending the first frame synchronization data, instrument coincidence counter TDync counting is 1, and after this counter adds up by the sub-frame number that sends;
Step 44, terminal detects descending synchronous signal channel, and does synchronous detecting and adjustment according to detected descending synchronous signal channel;
If success synchronously between terminal and the instrument, then after step 44, direct execution in step 45;
Step 45, instrument and terminal begin to carry out the up-downgoing calibration according to the TD-SCDMA frame structure;
Step 46, if judge synchronization failure between terminal and the instrument in the step 44, then terminal is notified to main frame with synchronization failure, and execution in step 47;
Step 47, main frame is notified to instrument with synchronization failure, finishes this calibration;
In step 45, if adopt aforesaid way two, then terminal is sending up calibration data after the success synchronously immediately, and begins to receive descending calibration data; Instrument continues to monitor the up calibration data of terminal after beginning to send descending synchronous signal channel (that is, beginning synchronously), if detect the data of self terminal, then begin to carry out the up-downgoing calibration, sends descending calibration data to terminal.
Wherein, carrying out after terminal enters the descending synchronous signal channel detected state, can detecting the power of descending synchronous signal channel all the time when synchronous, its concrete detection method is as follows:
Terminal receives the data (6400chips) of a subframe, and last 128chips data are copied to the foremost, the reception data that group is grown into 6400+128chips; Wherein, in j the sub-frame data that receives, be that the window of 128chips is with certain step-length (l with length
Step) slide, calculate the power ratio in each window:
Wherein, P
Left_iBe the power of 32chips before i the window, P
Right_iBe the power of 32chips behind i the window, P
Mid_iBe the power of middle 64chips, wherein,
Relatively more all power ratio R
i, find minimum ratio, be expressed as P
MinIf P
MinLess than thresholding λ, then detect descending synchronous signal channel, otherwise do not detect descending synchronous signal channel.
If counting equals T synchronously, terminal does not detect descending synchronous signal channel yet, then exports the sign of synchronization failure.
After detecting descending synchronous signal channel, terminal begins to adjust synchronously based on descending synchronous signal channel.Synchronization adjustment algorithm mainly is in order to make synchronization accuracy reach the chip level, and synchronization adjustment algorithm is known to those skilled in the art, and this paper no longer describes its detailed process in detail.According to the difference that synchronized algorithm is realized, when synchronization failure appears in algorithm, then export the sign of synchronization failure, otherwise the synchronous successful sign of output.
