Embodiment
Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
See figures.1.and.2, Fig. 1 is total received power and the difference Pr-Pn of thermal noise and the graph of relation of reverse load rate L of cdma system in the embodiment of the invention, and Fig. 2 is the graph of relation of interference margins ROT and reverse load rate L in the embodiment of the invention.
The power consumption of base station is the input power weighted average of measuring under with reference to the traffic load model in difference; The power output of base station be difference with reference to the traffic load model under the weighted average of measuring machine top power output; The input and output power ratio of base station is the ratio of machine top power output of power consumption and the base station of base station.
Suppose that cdma base station sub-district reverse load representes (0 < L < 1) with L, usually define system sub-district reverse load L is following:
L=M/N=actual user's number/theoretical maximum number of user.
Total received power under the whole bandwidth of each antenna opening of cdma base station, be designated as Pr (unit: dB), thermal noise be designated as Pn (unit: dB), Pr-Pn=-10lg (1-L) then.
Relation table between Pr-Pn and the system reverse load factor L is following:
| L | Pr-?Pn?(dB) |
| 25% | 1.25 |
| 50% | 3.01 |
| 75% | 6.02 |
| 90% | 10 |
| 99% | 20 |
Relation curve between Pr-Pn and the cdma system reverse load rate L is as shown in Figure 1, and load factor is high more, and Pr-Pn is big more.
The cdma system background noise is that thermal noise is: Pn=KBT (unit is mW);
Or: Pn=-174+10lgB (unit is dBm);
Wherein: K is the Boltzmann constant, is 1.380650 * 10
-23J/K;
T is an absolute temperature, is unit with Kelvin, and the mark temperature is 290K;
B receives bandwidth, as cdma system signal, B=1.23MHz.
Through calculating: Pn=-174 * 10 * log (1.23 * 10
6The 113dBm of)=-.
System noise or background noise that we are usually said just be-113dBm, if the CDMA signal be lower than-113dBm just is submerged in noise and suffered.Real background noise will be higher than this value, and this is because actual receiver also receives the influence of noise factor, comprises the energy consumption of filter, low noise amplifier (LNA), frequency mixer etc.
Base station cell RSSI (Received Signal Strength Indicator receives signal strength indication value) is exactly on the basis of thermal noise, the intensity level after all kinds of reverse signal stacks.In CDMA 1X system reverse power overload control algolithm and CDMA EVDO system reverse rate control algorithm, all need calculate cdma base station system reverse traffic load, base station system all reports the RSSI value.
RSSI reports backstage (can or diagnose TRX to obtain through backstage radio frequency real-time monitored instrument) by TRX (transceiver unit); RX veneer intermediate-frequency circuit in the TRX module detects the signal strength signal intensity of intermediate frequency; Deduct the link gain of antenna port to transceiver intermediate frequency power detection mouth; Obtain the signal strength signal intensity of antenna opening, report the backstage.
The relation of the interference margins of cdma system and system reverse traffic load is as follows:
The relation of reverse receiving intensity in sub-district and sub-district reverse load is following:
RP=TN+ROT，
Wherein: RP is the base station reverse receiving intensity, and TN is the thermal noise power in the pass band width.
ROT is an interference margins, defines as follows:
ROT=-10*lg(1-X)，
Wherein, X is the system reverse load.
There are relation one to one in ROT and X, and Fig. 2 has described this relation.
So: RP=TN-10*lg (1-X).
Suppose that TN is constant, then base station reverse receiving intensity RP also is an one-to-one relationship with X.
If the system reverse load reaches 75%, the RSSI long-time statistical is with rising 6dB; If the system reverse load reaches 50%, the RSSI long-time statistical is with rising 3dB; If system loading is lower than 20%, the RSSI long-time statistical is with not enough 1dB difference.That is to say that along with the increase of system loading, interference margins is constantly becoming big, this has also just confirmed cdma system is from the saying of disturbing system.
Relation between reverse receiving intensity and the cell load rate is: RP=Noisefloor+ROT=Noisefloor-10*lg (1-X).After reverse receiving intensity is removed thermal noise, i.e. interference margins, the relation between itself and the cell load rate is as shown in Figure 2.
The load of CDMA2000 1X is 75% to 80%, and the maximum of calculating interference margins so is:
ROT=-10*lg(1-X)=?-10*lg(1-0.8)=7dB。
That is to say that when system loading was 80%, the reverse RSSI of long-term statistics raise to about 7dB.
Above-mentioned analysis and calculating are the theoretical foundations of whole invention, guarantee the accuracy of reported data, that is to say the reliability of clear entire method.
Next, present embodiment will be described the relation of base station power output and amplifier power supply.
When power output is lower; The essential reason that power amplification efficiency is lower is that traditional DPD+Doherty power amplifier has adopted the fixed power source voltage method, and promptly power amplifier is exported in order to reach bigger power, and indexs such as the linearity are exported in assurance; Must use higher supply voltage; When the power amplifier power output is lower, also adopted higher supply voltage, efficient is low to be inevitable.Adopt the classification variable voltage, power supply is carried out intelligent management.When the power amplifier power output is bigger, bigger to the voltage of power amplifier power supply, and in the power amplifier power output; When being lower than certain value; Just reduce the supply power voltage of power amplifier, just, power output is divided into several grades for the different power output of power amplifier; Then each grade power output is adopted corresponding supply power voltage, improve to attack and put efficient.
When the LDMOS power tube is operated in the amplification condition, can change pipe drain electrode static working current Id, make power tube be operated in operation class (of an amplifying stage)s such as A, AB, B, C class, directly influence the linear index and the efficient of power amplifier through changing grid voltage Vgs.For given grid voltage Vgs, quiescent current Id substantially constant changes not obvious with drain voltage Vd.Like this, when the power amplifier power output is lower, just can reduces drain electrode operating voltage Vd and reach reduction power amplifier power consumption, improve power amplification efficiency.Export powerful the time when power amplifier, then need improve the Vd operating voltage, reach the saturation power that improves pipe, improve the performance of power amplifier.
To the characteristic of amplifier main devices amplifier tube, can according to power amplifier under the different output power state, change the drain electrode operating voltage, power supply is carried out intelligent management.When power amplifier needed power output bigger, bigger to the voltage of power amplifier power supply, and need power output hour at power amplifier, the supply power voltage that then reduces power amplifier to be improving power amplification efficiency, thereby reached pressure regulating energy-saving, improve the purpose of power amplification efficiency.
