Abstract
In this paper, we analyzed Alamouti based the MIMO-OFDM system in an underwater vertical communication channels. These in consideration both the transmission loss the multipath loss which is suitable for underwater environment are necessary method to improve the efficiency and communication performance in underwater communication. This paper is modeled in an environment that caused the error, considered each simulated the multi-path loss, transmission loss, the Doppler spread in order to implement a practical communication environment and simulated through the MIMO-OFDM system of Alamouti STBC method. The MIMO-OFDM system 2Tx-2Rx of Alamouti STBC scheme in underwater vertical communication system is obtained about 3~5 dB gain as compare with its 2Tx-1Rx scheme with reference $\small{10^{-3}}$ BER.
