摘要
针对OFDMA技术及无线局域网特性,介绍了基于OFDMA的信道接入流程,深入探讨了引入OFDMA需要解决的问题,包括无线资源分配、信道接入算法及隐藏节点问题,分析了引入OFDMA后可能带来的性能提升。
The process of channel access based on OFDMA was introduced. And then the problems needed to solve by introducing OFDMA were discussed, including the wireless resource allocation, channel access algorithm and the hidden nodes problem. Finally, performance improvement possible introduced by OFDMA was analyzed.
