【Abstract】 Space time block coding based on orthogonal design over Rayleigh fading channels uses multiple transmit antennas. The uses of the orthogonal structure and the maximum likelihood decoding algorithm reduce the complex of the receive, improve the performance of the system. STBC OFDM transmit technique and its performance are analysis.更多还原
