摘要

提出了一种基于正交频分多址(OFDMA)的无线局域网系统的自适应子信道和位分配方法。提出的自适应子信道和位分配方法结合了自适应子信道分配技术和自适应调制技术，提高了OFDMA系统的信道容量。计算机仿真结果表明，该方法在点对多点无线局域网系统中，即使在严重的频率选择性衰落环境下，也能获得较高的频率带宽效率和优良的信号质量。

Proposal of adaptive subchannel and bit allocation method for OFDM access wireless LAN systems

This paper proposes an adaptive subchannel and bit allocation method for OFDMA (orthogonal frequency division multiple access) based wireless LAN systems. The proposed adaptive subchannel and bit allocation method combines the adaptive subchannel allocation technique and adaptive modulation technique to improve the channel capacity of OFDMA system. This paper presents computer simulation results to demonstrate that the proposed method can achieve the higher frequency bandwidth efficiency and excellent signal quality even under severe frequency selective fading environment for point-to-multipoint wireless LAN systems.
