| Abstract(in English) | In Orthogonal-Frequency-Division-Multiplexing (OFDM) transmission systems, a Cyclic Prefix (CP) which length is corresponding to a maximum delay spread of an assumed delay profile of a channel is added to a head of each OFDM symbol as Guard Interval (GI) to alleviate an effect of multipath delay. However, in a particular environment, the long delay multipath which is over the length of CP may arise. In this case, the received OFDM signal is suffer from Inter Symbol Interference (ISI) and Inter Carrier Interference (ICI) which degrade the system performance. In this paper, we consider an iterative interference cancellation scheme including error correction decoding as a compensation scheme for multipath interference LDPC coded OFDM systems. |
