    摘要: 在本論文中,主要透過MATLAB軟體模擬Alamonti兩根傳送天線與M根接收天線的空時碼系統、以及推廣到四根傳送天線M根接收天線的空時方塊碼Space-Time Block Code(STBC),與一根傳送天線M根接收天線的傳統接收分集Receiver Diversity的Maximum Ratio Receiver Combining (MRRC)系統的效能比較。調變方面使用Quadrature Phase Shift Keying (QPSK),系統考慮高斯白雜訊Additive White Gaussian Noise(AWGN)與雷利衰減通道(Rayleigh Fading channel),而多重輸入多重輸入天線Multiple Input Multiple Output Antenna(MIMO)系統為主要探求之目標,最後在二傳二收與四傳四收的空時碼系統架構下加入正交分頻多工OFDM (Orthogonal Frequency Division Multiplexing) ,在雷利衰減通道(Rayleigh Fading Channel)下,做效能評估。
    In this thesis,it is mainly by utilizing MATLAB software to simulate the system performance between Alamonti scheme with M receiver antennas and Space-Time Block Code (STBC) with four transmit antennas and M receiver antennas. Also we simulated triditional receiver diversity Maximum Ratio Receiver Combining (MRRC) scheme. We compare system performance with different transmitting scheme. We are Quadrature Phase Shift Keying(QPSK) for the data transmission and it is assumed that the channel is formed by combining the Additive White Gaussian Noise (AWGN) and Rayleigh fading.We forcus on Multiple Input Multiple Output (MIMO) antennas ,and specifically we consider two transmitter antennas and two receiver antennas scheme and four transmitter antennas and four receiver antennas scheme by using OFDM (Orthogonal Frequency Division Multiplexing) in Rayleigh fading channel .
