| 摘 要： | 在微蜂窝小区用户速率比例公平约束条件下,以最大化系统和速率为目标,提出了一种改进资源分配算法,并用拉格朗日法求解优化功率.结果表明:相比于传统的最低比例速率的资源分配算法,本算法在频率和总功率固定的条件下,能减少计算复杂度,且系统速率提高了约2%.

| Abstract: | To optimize maximizing system rate,we propose an improved resource allocation algorithm based on the constraint conditions of rate proportional fairness,and solve the optimal power by using Lagrange method.The results show that,compared to the traditional resource allocation algorithm of minimum proportional rate,our algorithm can reduce computational complexity and improves the system rate effectively. |

| Keywords: | microcells resource allocation proportional fairness system rate |
