Embodiment Construction
[0030] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0031] The antenna and subcarrier allocation method based on the Nash bargaining solution involved in the present invention can jointly allocate antenna and subcarrier resources in a multi-user distributed MIMO-OFDM system, and can achieve an effective compromise between user fairness and system capacity performance .
[0032] The main idea of the present invention is: the present invention is an antenna and subcarrier allocation (MNBSASA, Multi-user Nash Bargaining Solution-based Antenna & Sub-carrier Allocation) method based on Nash Bargaining Solution, which is realized by the following technical solutions: first, according to the calculation complexity Tolerance sets the number of static ports for user communication (to ensure that the advantages of multi-port can be played, and part of the complexity can be reduced), and select a number ...
