Detailed Description
The principles and features of the present application are described below with examples given for the purpose of illustration only and are not intended to limit the scope of the application.
As shown in fig. 1, a frequency shift compensation method includes:
step 1, according to a sampling period, obtaining a plurality of peaks of an output signal of a 5G MIMO system through a peak detector, and calculating any peak to obtain a maximum power value in the current sampling period;
step 2, repeating the step 1 in the historical data until the maximum power value corresponding to m sampling periods is obtained, calculating a first average value of the m maximum power values, determining the traffic in each sampling period according to the average value, calculating a second average value of the m traffic, and determining the accurate power of the 5G MIMO system according to the first average value and the second average value, wherein m is a positive integer greater than 1;
and 3, when the traffic volume in the current sampling period is higher than a threshold value, adjusting the values of the output power of the direct channel and the variable frequency channel of the 5G MIMO system to be the value of the accurate power through an attenuator, and completing frequency shift compensation.
In some possible embodiments, by collecting and processing the output signals of the 5G MIMO system, the accurate power of the 5G MIMO system can be determined, and further frequency shift compensation can be performed based on the accurate power, so that the accuracy of compensation can be ensured.
It should be noted that, because of its energy-saving property, the 5G NR signal is difficult to detect the real signal power through analog detection, and the power information in the 5G NR signal is often understood from digital signals. Therefore, the application detects the output signal of the 5G MIMO system in the sampling period (such as 5 ms) through the peak detector, converts any detected data to obtain the power value corresponding to the data, and selects the maximum power value in the sampling period; for example: 100 data are detected in a sampling period of 5ms, and the data are all AD values, and note that the calculation method of the maximum power value in the sampling period is divided into two types:
1) The first way is: converting each AD value into a voltage value, converting each voltage value into a power value through a formula I, and determining a maximum power value from all power values through a formula II;
2) The second way is: and converting each AD value into a voltage value, selecting a maximum voltage value from all the voltage values, and converting the power value, wherein the converted power value is the maximum power value.
It should be further noted that, the AD sampling is realized by an ADC in the singlechip, the reference level is 3.3v, the sampling bit width is 12 bits, and the sampling rate is 200kh, so that the determination can be made at this timeWherein A is AD value.
S2, after determining the maximum power value in the current sampling period, determining the accurate power of the 5G MIMO system can be further performed, and the specific process is as follows:
s21, judging whether historical data exists before the current sampling period, and if so, completing the determination of the accurate power through the following process:
in the historical data, according to the method for determining the maximum power value, the maximum power value corresponding to each sampling period is determined, a first average value of all the maximum power values is calculated, the traffic in each sampling period is determined on the basis of the first average value, a second average value of all the traffic is calculated, and the accurate power of the 5G MIMO system can be determined on the basis of the first average value and the second average value.
It should be further explained here that the sampling period corresponds to the sub-frame duration of the NR signal.
For example, the historical data includes 20 sampling periods and data corresponding to each sampling period, according to actual requirements, five sampling periods closest to the current sampling period and data corresponding to the five sampling periods are selected, each period corresponds to 100 data, the maximum power values corresponding to the five sampling periods are calculated respectively, a first average value of the maximum power values of the five sampling periods is calculated through a formula seven, according to the first average value, how many of the 100 data in each sampling period exceeds the first average value is judged in sequence, the obtained proportion is used as traffic, and the traffic of the sampling period is calculated and obtained through a formula four and a formula five. According to the method for calculating the traffic volume, the traffic volume corresponding to the five sampling periods is calculated, the average value of the five traffic volumes is calculated again through a formula six to obtain a second average value, and the accurate power of the 5G MIMO system can be determined based on the first average value and the second average value through a formula eight.
S22, if no history data exists, the determination of the accurate power is completed through the following process:
and calculating the average value of all data in the current sampling period as a first average value, determining the traffic volume through the process, wherein the second average value at the moment is the traffic volume, and the subsequent processing process is the same as the processing process of the historical data.
Thus, the determination of the accurate power of the 5G MIMO system is completed, and the function is to ensure that the maximum output power is realized under high traffic and the two channels are balanced, and the low-power-consumption working mode is kept under low traffic. The process of completing the frequency shift compensation by using the accurate power is as follows:
s31, judging whether the traffic volume in the current period is higher than a threshold value, if so, then: adjusting the output power of a direct channel and a variable frequency channel of the 5G MIMO system so that the output power of the direct channel and the variable frequency channel is a first output power value;
and when the traffic is higher than 50%, the gain of the through channel is adjusted to the maximum gain supported by the equipment, and the variable frequency channel follows the adjusted gain according to the through output power value. So that the two-channel output power remains balanced. The output power of the variable frequency channel and the output power of the direct channel are the accurate power values calculated by the formula eight.
S32, if the threshold is lower, then:
and adjusting the output power of the through channel of the 5G MIMO system through an attenuator so as to reduce the gain of the through channel of the 5G MIMO system to 1/2 of that of the unadjusted through channel. And simultaneously closing a frequency conversion channel of the 5G MIMO system.
