摘要：

Real-time and reliable data transmission plays a key role in modern ocean resources exploitation and ocean environment detection systems. This paper presents the design and implementation of Discrete Fourier Transform Spread based Orthogonal Frequency Division Multiplexing (DFT-Spread OFDM) system with TMS320C6713 DSP over underwater acoustic (UWA) channels. DFT-Spread OFDM is a promising high date rate and low bit error rate data transmission alternative which gets not only the advantages of OFDM but also low peak-to-average power ratio. Simulations and the experiment pool results demonstrate that the system has good real-time processing capability, system stability. And the implementation effort provides some useful references for realizing a practical modem for high-data-rate and reliable underwater acoustic communications.
