| Abstract(in English) | In mobile communication systems with MC-CDM, a multi-path effect can be reduced by addition of a guard interval to a transmitted symbol stream. However, A multi-path wave with a delay time exceeding the guard interval (GI) length degrades the error rate performance. In this paper, we propose a multi-path interference canceller to improve the error rate performance for downlink in the MC-CDM systems. An interference level can be reduced by an exchange of interfered samples with replica samples that are obtained by a decision feedback. A computer simulation is carried out to estimate the canceller performance. This simulation results show taht the proposed canceller could be applied to propagation environments in the presence of multi-path waves with a delay time exceeding double the GI length. |
