| 摘要 |
Underwater communications apparatus and methods are presented using iterative correlation-based equalization in which initial estimated symbols of a current data block are produced using a correlation-based equalizer (CBE) based at least partially on the received sound transmissions of the current data block and an estimated channel impulse response (CIR) of a previous data block, the CIR of the current data block is estimated using the initial estimated symbols, and re-estimated symbols of the current data block are produced using a CBE based on the estimated CIR, and the estimated symbol having the lowest error is selected as the received data.
