In DS-CDMA uplink transmission without guard interval (GI), the block detection suffered from inter block interference (IBI) and circular property (CP) loss due to the multi-path fading channel. Therefore, IBI cancellation and CP compensation have to be carried out in order to restore the transmitted signal. It is verified that, CP compensation is more effective than IBI cancelation, while the condition is perfect channel estimation in a uniform power delay channel model. In this paper, more practical channel models with imperfect channel estimation will be applied. And the corresponding performance of the IBI cancellation and CP compensation will be evaluated by simulation results. |
