Multiple-Symbol Encapsulated Orthogonal Frequency Division Multiplexing Communication in Multipath Underwater Acoustic Channel

In this paper, multiple-symbol encapsulated orthogonal frequency division multiplexing (MSE-OFDM) is proposed to be employed in a multipath fading channel. Simulation results demonstrate that this method is particularly suitable for channels with long impulse response. MSE-OFDM combined with the spatial diversity technique yields a significant improvement in bandwidth efficiency even in a low signal-to-noise ratio (SNR) environment.
