Because the channel capacity of existing round robin scheduling is low, a multi-user diversity algorithm cannot consider the fairness among users.

由于现有的轮询算法系统容量较低，而多用户分集算法无法考虑用户的公平性。

In case of single-cell OFDMA system, the study ranges from single user power allocation, multi-user subcarrier scheduling to joint subcarrier and power allocation.

并重点从功率分配和子载波调度方面对OFDMA系统的资源分配进行了研究和仿真。
