摘要

首先介绍目前无线通信中常用的3种调度算法。为了提高频谱利用率

通过仿真比较了3种常用调度算法对系统性能的影响

提出基于QoS（服务质量）业务的比例公平调度算法。该调度算法兼容了其他调度算法的优点。实验中对用户配置不同的QoS参数

从吞吐量的角度来验证不同配置的用户有不同的吞吐量

而且系统会优先保障最优用户的需求。该调度算法提高了系统的最大吞吐量

满足了用户调度的公平性

给用户提供了不同的业务服务

保障了用户的不同需求。

Abstract

This paper introduces three kinds of scheduling algorithms commonly used in wireless correspondence.In order to improve the spectrum utilization rate

it proposes a QoS-based Proportional Fair（PF） scheduling algorithm on the basis of comparing the influences of these three algorithms on the system performances.This algorithm incorporates the advantages of the other scheduling algorithms.In the experiment

it allocates the users with different QoS parameters and the users with different allocations have different throughputs.Furthermore

the system gives priority to the needs of the optimal users.This algorithm improves the maximum throughput of the system

ensures the fairness of user scheduling

provides the users with different services and satisfies the different needs of the users.
