Study on IBI cancellation and CP restoration in DS-CDMA uplink transmission

摘要

In DS-CDMA uplink transmission, the block detection suffered from inter block interference (IBI) and power loss due to the multi-path fading channel. Therefore, IBI cancellation and power loss compensation have to be carried out in order to restore the transmitted signal. In this paper, the principle of IBI cancellation and power loss compensation will be presented. And the performance of the IBI cancellation and power loss compensation will be evaluated by simulation results.
