Abstract
The invention discloses a method for optimizing terminal tone of code division multiple accessing network, and includes the following steps: (a). transmit the original frequency response curve data tested by the audio frequency testing instrument into the system; (b). automatically calculate the filter according to the gaining setting of users at each frequency point, and draw the filter's response curve and compound frequency response curve; (c). store or install debugging process data on PC in document format; (d). display the qualification scope of frequency response curve, and read/write sound frequency response, echo restraining, noise restraining, volume parameters through mobile phones' IO port. The invention enhances the precision of parameters through software emulation, modifies related parameters through communication ports of mobile phones, and enters data through audio frequency testing instrument, so as to enhance audio frequency feature debugging efficiency of terminal products.
Description
Technical field
The present invention relates to communication technical field, relate in particular to the method for a kind of optimization CDMA (CDMA) terminal tonequality.
Background technology
The acoustic characteristic of CDMA terminal is very important, can directly have influence on user's actual use, so audio frequency debugging is necessary procedure in the CDMA terminal development process, mainly comprises processes such as frequency response curve debugging, echo inhibition, squelch.
Existing C DMA end product mainly uses the CDMA nest plate of Qualcomm.Baseband chip is wherein topmost chip; Accomplished the major function during whole C DMA handles; Comprising encoding and decoding speech and analog audio interface; Functions such as sound frequency response, echo inhibition, squelch, volume all are solidificated in the code, cause sound partly to debug very difficulty.
The method of the acoustic characteristic of existing adjusting end product is according to test result estimation parameter, changes code, compiles, downloads the file into mobile phone, and test again, so repeatedly.This method debugging efficiency and parameter degree of accuracy are all very low.
Summary of the invention
Technical matters to be solved by this invention provides the method for a kind of CDMA of optimization terminal tonequality, improves debugging efficiency and parameter degree of accuracy.
For solving the problems of the technologies described above, the present invention realizes through following technical scheme:
A kind of method of optimizing CDMA network terminal tone quality may further comprise the steps:
A: the original frequency response curve data importing system of audio-frequency test appearance test;
B: in the gain of each frequency automatic calculating filter is set according to the user, and draws filter response curve and synthetic frequency response curve;
C: be implemented in PC and go up with the file layout preservation or the debug process data of packing into;
D, show the acceptability limit of frequency response curve, and the IO port through mobile phone, the response of read/write sound frequency, echo inhibition, squelch, volume parameter.
Wherein, comprise also between step a and the step b that the synthetic frequency response curve of adjustment is to debugging person's claimed range.
Wherein, the data layout that imports among the step a is exp form or excel form.
The present invention has following beneficial effect:
The present invention improves the parameter degree of accuracy through using software emulation; Through the function of increase mobile communication port modifications correlation parameter, and utilize the audio-frequency test instrument to import data, thereby improve the acoustic characteristic debugging efficiency of end product.
Description of drawings
Fig. 1 is the inventive method process flow diagram.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:
At the PC end, the frequency response debugging is provided with automatic calculating filter according to the user in the gain of each frequency, draws out the response curve of wave filter, and comes out the effect simulation behind the increase wave filter automatically.Debugging person is provided with the gain of respective frequencies point according to original frequency response curve figure, gets final product automatic designing filter, draws filter response curve and synthetic frequency response curve.The synthetic frequency response curve of adjustment is produced filter coefficient behind debugging person's claimed range, accomplish Design of Filter.
The frequency response simulation provides data I mport, Save, Load function.Data I mport is the original frequency response curve data importing system of audio-frequency test appearance test.Import data layout and support the exp form of RS company audio-frequency test appearance derivation and the test result of excel form.Importing data layout as required can also expand, to support different audio-frequency test appearance.Save/Load realizes preserving or the debug process data of packing into.When the commissioning staff accomplished Design of Filter, system default was preserved current tune-up data, when the user gets into system once more, and these data of packing into automatically.Realized automatically restoring to the state when withdrawing from last time when the user gets into system once more, the user can continue debugging on this basis.
Through the IO port of mobile phone, system reads correlation parameters such as squelch, echo inhibition, volume adjusting from mobile phone.After designing parameter on the PC, the mobile phone that writes direct can come into force.
At embedded end, the parameter that is solidificated in the code, be kept among the NV (nonvolatilememory), from NV, read the parameter initialization mobile phone behind the handset starting.After receiving that PC reads parameter command, return to PC to the parameter among the NV; Receive that writing NV to a parameter that designs behind the write order that PC transmits preserves, the line correlation of going forward side by side realizes that synchronously parameter comes into force.
See also shown in Figure 1ly, this method may further comprise the steps:
Step 101: the original frequency response curve data importing system of audio-frequency test appearance test;
Step 102: in the gain of each frequency automatic calculating filter is set according to the user; And drafting filter response curve and synthetic frequency response curve; Up to the complete target approach curve ranges of synthetic frequency response curve; Just can satisfy the requirement of 3gpp2 to frequency response, on this basis can be according to subjective feeling to tonequality, tonequality is finely tuned with optimum efficiency on earth;
Step 103: be implemented in PC and go up with the file layout preservation or the debug process data of packing into;
Step 104: show the acceptability limit of frequency response curve, and pass through the IO port of mobile phone, the response of read/write sound frequency, echo inhibition, squelch, volume parameter.
The above is merely preferred embodiment of the present invention, not in order to restriction the present invention, all any modifications of within spirit of the present invention and principle, being done, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
