  • A signal detection and synchronization acquisition scheme is proposed for distributed Multiple Input Multiple Output Orthogonal Frequency Division Multiplexing (MIMO-OFDM) system. Reliable signal detection scheme and coarse time and coarse frequency estimation based on spectrum analysis method can be obtained by designing pilot symbols. And then the pilot symbols are used for POST-Fast Fourier Transform (FFT) precisely frequency and time estimation. The simulation results show that the new algorithm works well at low SNR over wireless multipath channel.
