摘要
从浅海声信道的特性出发 ,研究水下声信道的多径时延 ,提出自适应模型 ,给出水声信道自适应模拟的方法 ,以达到对水声多径信道的计算机模拟。模型的建立适合于自适应算法 ,较为简洁 ,在保证估计精度的情况下 ,可减少计算量 。
Based on the analysis of shallow acoustic water channel, the article discuss its multipath time delay, and put forward an adaptive model and the method of underwater adaptive simulation to lessen the effect from multipathing. In the condition of the same estimating precision,the model is concise and effective to fit adaptive arithmetic and reduce calculation.To simplify multipath model is a way to research the property of underwater channel.
