In this paper, we propose a reliable communication solution using space-time diversity technique but using only one transceiver antenna applied to mobile OFDM system in underwater communication environment. In our solution, instead of using multiple receive antennas, the transmitter transmits an OFDM signal N times consecutively.

In this thesis, the two systems are simulated with particular parameters and the performance of Bit Error Rate (BER) is evaluated to determine the different types of wavelets in various channel conditions with separate modulation methods (8, 16, 32-QAM). Therefore, MIMO-OFDM system based on DWT algorithm will be compared with MIMO-OFDM system based on FFT algorithm by using MATLAB simulation software.

In this paper, we propose a fine time synchronization for a Multiple Input Multiple Output Orthogonal Frequency Division Multiplexing (MIMO-OFDM) system. The proposed algorithm uses one more IFFT to find the timing offset, then correct it. The simulations show that comparing to the conventional algorithm using cross-correlation method, the proposed algorithm has a higher timing detection probability.

The paper concentrates on researching the pipeline architecture that utilize only one IFFT block for two antennas, especially butterfly type. Two design schematics are used, including Sysgen and direct Vivado. The first architecture guarantees the function of the signal processing like the latter while using less the resource.

Orthogonal frequency division multiplexing (OFDM) has become a prevalent and widespread technique for the broadcast and transmission of signals over wireless channels and has been adopted in many wireless standards. OFDM may be united with antenna arrays at the transmitter and receiver side to improve the diversity gain and to improve the system competence on time-variant along with the frequency-selective channels, resulting in a multiple-input multiple-output (MIMO) composition.

In this paper, we focus on MIMO-OFDM systems that simultaneously perform channel estimation in order to combat additive noise, and multipath fading. The performance improvement is confirmed by simulations. Results show that the proposed MIMOOFDM scheme is quite robust in practical environments.
