Abstract
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.
