Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
First smart antenna coupling disc, circulator, power splitter are described:
Fig. 1 is smart antenna coupling disc structural representation, and as shown in the figure, smart antenna coupling disc is comprised of 9 input ports and 8 output ports.9 input ports comprise: 8 I/O port (RF connector)+1cal Port forms.8 output ports are comprised of 8 Antenna element RF connector port.
The effect of circulator is: supposes, from 3 port output signals, by port one, to port 2, to be led to, but obstructed to port one by port 2, for logical, reverse obstructed along hoop, by that analogy; Take Figure 11 as example, and its effect is that frequency spectrograph can be accepted the signal of hair updo that is coupled, but can not receive the signal of signal source, and the signal of signal source can be dealt into coupling disc, but the signal of coupling disc can not be dealt into signal source.
Power splitter is the power splitter of one-to-two, and wherein, a mouth is connected with coupling disc calibration mouthful; Two mouths along separate routes, one is connected with the calibration mouth of base station RRU, while being used for calibrating, RRU calibrating signal can arrive coupling disc, another is connected with circulator, signal source signal, the calibration mouth by coupling disc is dealt into each radio frequency interface of RRU when testing, and after the radiofrequency signal of each radio frequency interface of RRU being combined, is dealt into frequency spectrograph simultaneously.
Secondly base station calibration process is described:
Antenna calibration process will be carried out after setting up carrier wave in base station.Antenna calibration is divided into sending calibration and receiving to be calibrated.While sending calibration, calibration path is in accepting state, and active channel is in transmission state, and the calibrating sequence that the utilization of calibration path receives calculates phase place and the amplitude error of each path, and produces antenna factor
during close alignment, calibration path is in transmission state, and active channel is in accepting state, and the calibrating sequence that each active channel utilization receives the transmission of calibration path calculates its phase place and amplitude, and produces antenna factor
RRU(Radio Remote Unit, Remote Radio Unit) inner from BBU(BaseBand Unit, baseband processing unit) each passage base band data of sending out and the antenna factor F of respective channel
send outmultiply each other, be transformed into afterwards radiofrequency signal and sent by radio frequency interface; Above-below direction transfers after baseband signal the antenna factor F with each passage to the signal of radio frequency interface
receivemultiply each other, send to BBU.Through said process, it is consistent that the signal phase that is input to each radio-frequency channel in RRU from coupling disc calibration interface and amplitude are just compensated for as, and the signal attenuation from each radio-frequency channel to coupling disc calibration interface simultaneously is also compensated for as consistent with phase deviation.
Then the algorithm of RRU is revised and is described:
In force, can be by debugging PC(Personal Computer, PC) issue mono-group of sending alignment compensating factor of RRU
with one group of close alignment compensating factor
after multiplying each other with calibration factor, be replaced by new calibration factor:
With
From the result of complex multiplication, see it is to send out at each passage
,contracture has not compensated phase factor
Finally to calculating the schematic diagram of phase difference value, be introduced.

360*（dn-d1）/λ （n=2～8）
Wherein, dn-d1=(n-1) * δ * cos (α).
3, in like manner, when sending out position and antenna distant, approximately think that the line of receiving position and each bay is parallel lines, sending out position and antenna tangent line angle is β, and the phase difference between each antenna calculates by formula below:
360*（dn-d1）/λ （n=2～8）
