Abstract
In the future, wireless broadband communication systems will not only be used for private access, but also public access with high data rate. The problems in transmitting high data rate at high speed mobility are how to provide wide bandwidth in rapidly changing channel condition, to mitigate selective fading problems, to estimate response of the channel, and to solve degradation of signal performance. We propose a comprehensive solution for those problems, i.e. modified MC-CDMA inner coding system model in MIMO wireless systems. We also consider that this system can accommodate multi user with multi services, various bandwidth usage, QoS or channel response for every user. The simulation result shows that the MIMO wireless system with the proposed inner coding in non coherent channel transmission scheme provides a good system performance. The proposed scheme can outperform other previously published inner coding schemes for high mobility, high Eb/N0 and multi user conditions. Copyright 2004 ACM.
