| Abstract(in English) | Recent underwater acoustic communication has adopted frequency domain equalization (FDE) for countermeasure of multipath. If a delay spread of multipath is within a cyclic prefix (CP), FDE is effective in compensating channel distortion. However, very long delay waves should be considered when reflected waves arrive from water surfaces, water bottoms, and obstacles in shallow sea environment. A long CP is disadvantageous in terms of transmission rate and communication response. This study considers underwater acoustic communication with a short CP under long delay multipath environment. Inter-block interference (IBI) and inter-carrier interference (ICI) are always present in the aforementioned environment. Single carrier frequency domain equalization (SC-FDE) has smaller influences of IBI and ICI and keeps better communication performance in QPSK transmission when compared to OFDM. |
