Thats a unique idea.You should consider the following idea to enhance your idea so that it would impact uniquely:  presents a digital signal processor (DSP) based iterative orthogonal frequency division multiplexing (OFDM) receiver for time-varying underwater acoustic channels. The time-varying channel is modelled by basis expansion model (BEM). To explore the inherent sparsity of underwater acoustic channel, orthogonal matching pursuit (OMP) algorithm is adopted. A fast Fourier transform (FFT) based low-complexity implementation of OMP algorithm is employed to reduce computational complexity and save memory space. The receiving system is implemented on a multi-core DSP evaluation module TMDX-EVM6678L. The performance of proposed receiving system is validated through experimental data collected from real world. With two cores running at 1 GHz, the real-time processing is achieved and the system performance is satisfying.
