摘要

针对WLAN

提出了一个基于多包接收的跨层资源分配方案.本文首先给出多个用户"共享"子信道的条件

并提出了子信道"独占"和"共享"混合模式的信道分配方案;然后

推导了满足用户QoS要求的功率和比特加载表达式.仿真结果表明:本文提出方案不仅能有效提高系统吞吐量

而且能降低平均包延时;并且具有计算复杂度低的特点.

Abstract

Tailored for the WLAN

we propose a cross-layer resource allocation schemes based on multi-packet reception.Firstly

the condition of sharing the subchannel by more than one user is obtained.Secondly

the subchannel allocation scheme including "exclusive" and "share" modes are proposed.Finally

the expression of power and bit loading which meets the QoS requirement is derived.Analysis and simulation show that proposed scheme not only improves the system throughput efficiently but also reduces the average packet delay and has low computational complexity.
