In number function, obtained value is determined as the element that the i-th row jth arranges in sign matrix.
Step 204：X-axis projection is carried out to sign matrix, obtains the first projection vector, Y-axis projection is carried out to sign matrix,
Obtain the second projection vector.
Specifically, it is to the process of sign matrix progress X-axis projection：Determine the of every a line all elements of sign matrix
One adds up and the first of all rows the cumulative and composition vector is determined as the first projection vector.That is, determining all members of the first row
Element first it is cumulative and, determine the second row all elements first it is cumulative and ... ..., until determining last column all elements
First it is cumulative and, these are first cumulative and according to the sequence from the first row to last column, form the first projection vector.
To sign matrix carry out Y-axis projection process be：Determine that the second of each row all elements of sign matrix add up
With the second of all row the cumulative and composition vector is determined as the second projection vector.That is, determining the of first row all elements
Two it is cumulative and, determine secondary series all elements second it is cumulative and ... ..., until determining the second tired of last row all elements
Adduction, these are second cumulative and according to sequence arrange from first row to last, the second projection vector of composition.
Step 205：According to the first projection vector and the second projection vector, definitive result vector.
A kind of possible realization method is to take absolute value respectively to the first projection vector and the element in the second projection vector
Afterwards, the element of corresponding position is added, and after will add up and composition of vector is determined as result vector.
Alternatively possible realization method is, after taking absolute value to the element in the first projection vector, it is default to be multiplied by first
Parameter forms treated the first projection vector, after taking absolute value to the element in the second projection vector, is multiplied by the second default ginseng
Number forms treated the second projection vector, wherein the second parameter preset is more than the first parameter preset；It will treated first
Element in projection vector is added with the element of treated the second projection vector corresponding position, after will add up and composition
Vector be determined as result vector.
Optionally, the first parameter preset can be 0.2, and the second parameter preset can be 0.8.To in the first projection vector
The element that element is multiplied by after taking absolute value in the first parameter preset and the second projection vector is multiplied by the second default ginseng after taking absolute value
Number, can adjust the weight of the element in result vector in the first projection vector and the element in the second projection vector.Due to
Two parameter presets are more than the first parameter preset, then are equivalent to the power for increasing the element in result vector in the second projection vector
Weight, convenient for improving the accuracy of the optimal frequency point subsequently determined.
Step 206：The corresponding candidate frequency point of maximum value in result vector is determined as optimal frequency point.
In a kind of possible realization method, only there are one maximum values in result vector, by the corresponding candidate frequency of the maximum value
Point is determined as optimal frequency point.Detailed process is the position where maximum value in definitive result vector, by candidate frequency point sequence, most
The corresponding candidate frequency point in position where big value is determined as the optimal frequency point.For example, the 5th element is maximum in result vector
Value, then by candidate frequency point sequence, the 5th candidate frequency point is determined as optimal frequency point.
It further include the reference letter of the corresponding candidate frequency point of macro station information in alternatively possible realization method, in macro station information
Number receive power (Reference Signal Received Power, RSRP).In the realization method, have in result vector
Multiple maximum values, it is determined that the process of optimal frequency point is：Each RSRP of the corresponding multiple candidate frequency points of determining maximum, will be more
In a RSRP, the corresponding candidate frequency points of maximum RSRP are determined as optimal frequency point.That is, when having multiple maximum values in result vector,
Optimal frequency point is determined in conjunction with the RSRP of the corresponding candidate frequency point of maximum value.
After determining optimal frequency point, the small stations LTE send out radiofrequency signal according to the optimal frequency point.
The above process is illustrated with a specific example below.
Assuming that the candidate frequency point in the embodiment of the present invention is 5, the corresponding candidate frequency point number (frequency point of this 5 candidate's frequency points
There is number between frequency point one-to-one relationship, the frequency point number in this example can be equivalent to the frequency point in above-described embodiment) respectively
