The Blind Identification of Multi-Inputs and Multi-Outputs Shallow-Water Acoustic Channel

摘要：

Blind channel identification/estimation is very important for object detection, trace,localization in the ocean acoustics. Time domain blind identification algorithm requiring exact length of the channel being identification. Due to the characteristics of the shallow-water channel, the length of channel impulse response sequence is uncertain, Hence a frequency domain method for the blind MIMO (Multiple-Input Multiple-Output) underwater identification based on higher order statistics (HOS) is used to estimate the original acoustic channel from received signals on hydrophones only, with the low signal to noise ratio (SNR).The simulation results in the acoustic environment proved this work is effective and efficient for blind identification of the shallow-water acoustic channel.
