New channel estimation, tracking and equalization algorithms for real-time high-speed underwater acoustic communication systems

高速水下通信对于澳大利亚海上石油和天然气工业、海上商业运营和国防应用至关重要。然而，由于恶劣的水下信道所带来的挑战，目前的水下通信系统的数据速率和误码率有显着的限制，为许多应用和环境。本计画旨在发展一个即时讯号处理平台，以在极有限频带及混响的水声信道中进行可靠的高速通讯。新的信道估计，跟踪和均衡算法在这个项目中开发将显着提高水下通信系统的容量。

High-speed underwater communication is vitally important for Australian offshore oil and gas industries, marine commercial operations, and defence applications. However, due to the challenges posed by the harsh underwater channel, current underwater communication systems have significant limitations on data rate and bit-error-rate for many applications and environments. This project aims to develop a real-time signal processing platform for reliable high-speed communication through the extremely bandlimited and reverberant underwater acoustic channel. New channel estimation, tracking and equalisation algorithms developed in this project will significantly enhance the capacity of underwater communication systems.
