User is divided into into the user's group with the quantity equal amount of Port resources, to generate the mistake of user grouping information
Journey, the process can be accomplished in several ways, and the present embodiment provides following three kinds of implementations, is based on
Below the thought of three kinds of implementations it is developed other modes also in the protection domain of the application：
Mode one：
User is divided into into multiple user's groups；
The overall relevancy of the plurality of user's group is calculated, the overall relevancy is every in the plurality of user's group
End-user relevance sum in the group of individual user's group, in described group, End-user relevance is between the user in user's group
Dependency sum；
The dividing mode of the plurality of user's group is adjusted, so that the overall relevancy is minimum；
Mode two：

Dependency sum；
The dividing mode of the plurality of user's group is adjusted, and Second Threshold is reached until adjusting number of times.
Explanation is needed further exist for, what is referred in above-mentioned three kinds of modes " is divided into multiple use by user
In the step for family group ", user can be divided into into the quantity use equal with the quantity of Port resources directly
Family group, it is also possible to first by the user's group that user's division numbers are the quantity less than Port resources, then choose group
The maximum group of interior End-user relevance, then divided, until the user's group quantity for dividing and Port resources
Till quantity is equal, in this regard, the present embodiment does not do any restriction.
Further it should be noted that what is referred in above-mentioned three kinds of modes " calculates the plurality of user
In the step for overall relevancy of group ", the dependency in user's group between user will be first calculated.
In the present embodiment, the dependency in user's group between user is employed and is defined as below：
Wherein, cijFor the dependency of user i and user j,It is user i and user j in n-th section of bandwidth
On dependency.RinAverage or instantaneous down channel covariances of the user i in n-th section of bandwidth.Common N
Section bandwidth, winFor emission values of the user i in n-th section of bandwidth, wjnIt is user j in n-th section of bandwidth
On emission value, H represents conjugate transpose.
Based on above-mentioned definition, the dependency in user's group between user can be calculated according to above-mentioned formula.
Then, the dependency sum between the user in user's group is calculated to obtain the dependency of user in group：
Finally, the dependency of user in each group is added the overall relevancy for obtaining multiple user's groups.
Further it should be noted that " the plurality of user of adjustment referred in above-mentioned three kinds of modes
In the step for dividing mode of group ", it is to shift or exchange the user in each user's group, is made per group as far as possible
In the group of user, End-user relevance meets following object function：
Wherein, K is group number, and its value is equal with the quantity of Port resources, GKFor the set of K group users.
That is, ensure that the weak user of dependency is divided into one group between user as far as possible, i.e., ensure per group as far as possible
In the group of user, End-user relevance is minimum, so as to the overall relevancy for ensureing multiple user's groups is minimum, if nothing
Method ensures that the overall relevancy of multiple user's groups is minimum, then can pre-set one according to concrete application scene
The corresponding first threshold of annoyance level can be born, makes the overall relevancy of multiple user's groups be less than first threshold
Value, if no matter how adjusting the dividing mode of multiple user's groups it cannot be guaranteed that total phase of multiple user's groups
Closing property is minimum or is less than the first threshold, then, when can arrange adjustment number of times and reaching Second Threshold, stop adjusting
It is whole, and the corresponding packet situation of value of minimum in corresponding each overall relevancy is adjusted before taking as final
User grouping, to avoid the carrying out for ceaselessly adjusting and affecting channel estimation.
S102, the dependency in the multiple user's groups of calculating between each two user's group.
In the present embodiment, the dependency between user's group u and user's group v is defined as：
Wherein, cijFor the dependency of user i and user j, GuUser for user's group u gathers, GvIt is use
User's set of family group v.
Based on above-mentioned definition, can be according between each two user's group in the multiple user's groups of above-mentioned formula calculating
Dependency.
S103, according to the dependency between each user's group, by each two user's group in the plurality of user's group
The user's group of composition is to being divided to first set or second set.
Wherein, the inter-class correlation of any one user's group pair in the first set is all higher than or waits
The inter-class correlation of any one user's group pair in the second set.
In this step, can be orthogonal according to what is included in the dependency between each user's group and Port resources
The user's group that each two user's group in multiple user's groups is constituted is divided by the number of Port resources, specifically
, the user's group that the number of orthogonal Port resources can be included as in first set is used to the difference being related to
The number of family group, can select to be divided to according to the descending order of the dependency between user's group successively
User's group pair in one set.Such as, it is assumed that have 4 user's groups A1, A2, A3, A4, according to
The user's group of the descending arrangement of family inter-class correlation is to being followed successively by：A1+A2, A1+A3, A1+A4,
A2+A3, A2+A4, A3+A4, Port resource has four B1, B2, B3, B4, wherein orthogonal Port
Resource is B1 and B2 two, then the user's group of correlation maximum is divided to the to (that is, A1+A2)
One set, by remaining user's group to (that is, A1+A3, A1+A4, A2+A3, A2+A4, A3+A4)
It is divided to second set.
S104, by the user's group in the first set to distributing in orthogonal Port resources, will be described
User's group in second set is to distribution in pseudo-orthogonal Port resources.
Specifically, the user's group included in first set is distributed orthogonal to the different user groups being related to
In Port resources, by the user's group included in second set to being related to except the difference that first set is related to is used
Other users component outside the group of family is fitted in pseudo-orthogonal Port resources.Such as, by above-mentioned A1 and A2
