Summary:
In a wireless propagation channel, the channel for each user is independent. By using this characteristic, orthogonal frequency division multiple access (OFDMA) with the multiuser diversity (MUDiv) effect is achieved. However, in the fast fading channel, since channel state information (CSI) is changed between the head and latter of packets, the system performance is degraded. Moreover, in this case, CSI is also changed between the cases with and without the feedback delay. To solve these problems, in this paper, we propose the compensation of the deteriorated CSI allocation based on the decision direct and the turbo equalization for MUDiv/OFDMA systems.
