Pilots Updating Channel Compensation Base on Underwater MIMO-OFDM

Abstract:

The communication rate is limited extremely by the confined bandwidth source of UWA (underwater acoustic) channel. MIMO (Multiple-input Multiple-output) techniques can drastically improve the spectral efficiency, and have been a new hot spot in UWA commutation. To estimate the UWA channel STBC (space-time block code) technique is adopted, and the improved method of channel estimating is also given. A designed of complex coding MIMO-OFDM is provided.The validity and the dependability of the scheme are verified by Monte Carlo simulations.
