Abstract

Underwater Acoustic (UWA) communication systems support low data rate, and have bad performance as compared to traditional wireless systems. This is due to attenuation, ambient noise, water salinity, temperature, etc. Hence, channel coding is introduced in order to enhance the UWA system performance. This paper presents a joint Frequency Domain Equalization (FDE) and Low Density Parity Check (LDPC) coding scheme in UWA Orthogonal Frequency Division Multiplexing (OFDM) in order to reduce the effect of the UWA system poor link. The proposed UWA system performance is evaluated via extensive simulations over different channels. Simulation results show that the proposed equalization with LDPC codes gives a good improvement in the UWA system performance.
