摘要

WiMAX系统受到频率选择性衰落的影响较大

而WiMAX系统的分布式子载波排列的载波分配方法可以将频率选择性衰落分散化

从而较好的解决频率选择性衰落的问题

并且由于这种载波分配方法使得各子信道的SINR相差不大

可以增加WiMAX系统的用户接入概率

减小网络开销

并减少了干扰的突发性

从而提高网络的性能。

Abstract

Frequency selective fading has an important effect on the data transmission in WiMAX system. However

the distributed usage of sub-channel can disperse the impact of frequency selective fading and average the SINR of sub-channel. It can not only increase the access probability of users but also minish the spending of network

reduce the outburst of interference and increase the performance of system.
