Description: 研究相关瑞利衰落信道上MIMO系统中组合发射机选择合并(SC)/4t-收机最大比合并(MRC)的天线分集系统性能。使用矩生成函数方法,推导相关瑞利衰落信道上采用组合SC/MRC天线分集和相干检测的M 进制相移键控(MPSK),M进制正交幅度调制(MQAM),M 进制脉冲幅度调制(MPAM)等几种M 进制数字调制方式的误符号率精确表达式。数值计算结果阐明相关性和天线阵结构对采用组合SC/MRC天线分集的几种M 进制数字调制方式的平均误符号率性能的影响。-Research related to Rayleigh fading MIMO channel transmitter system to choose the combined portfolio (SC)/4t-collection machine maximal-ratio combining (MRC) diversity antenna system performance. The use of moment generating function method, Rayleigh fading channel is derived using the relevant combination of SC/MRC antenna diversity and coherent detection of M-ary phase shift keying (MPSK), M M-ary quadrature amplitude modulation (MQAM), M-band pulse amplitude modulation (MPAM), such as several M-band digital modulation modes of expression of symbol error rate of accuracy. The numerical results clarify the relevance and structure of antenna arrays using combinations of SC/MRC antenna diversity of several M-band digital modulation of the average symbol error rate performance.

Description: 主函数Alamouti(Nr,max_snr,max_err_symbol,symbol_per_frame)
调用函数QpskMapping(psudo_bit_sequence)--二进制数据到QPSK信号的变换
调用函数RayleighCH(Nr,Nt)--瑞利衰落信道模拟
仿真示例:
Alamouti(1,12,20,24)
说明:
1.2根发射天线、1根接收天线
2.最高信噪比为12dB,即仿真范围为0dB到12dB
3.在每个信噪比条件下,误符号数超过20即停止该信噪比条件下的仿真
4.每一帧数据为24个QPSK符号
综合仿真函数SimAlamouti(max_snr,max_err_symbol,symbol_per_frame)
具有一根接收天线系统的SER性能与二根接收天线的系统SER性能比较
SimAlamouti(12,20,24)
参数说明:
1.max_err_symbol的取值直接影响了仿真的精度:取值越大,精度越高,误符号率曲线也更平滑;但需更长的仿真
时间
2.一般max_snr小于15dB,程序中snr为信号噪声功率比
3.本程序仿真时未考虑帧与帧之间,信道衰落系数的相关性,因此symbol_per_frame一定程度上表征了信道相关时
间的大小,即在symbol_per_frame个QPSK信号发送时间内,信道衰落系数是不变或缓变的,而在下一帧数据中,
信道衰落系数可以认为已变成另一值
4.本程序假定在接收端已通过信道估计获得信道衰落系数-ALAMOUTI performs Monte-Carlo simulation and estimates Bit Error Rate
(BER) of Alamouti Scheme [1] over Rayleigh channel. The scheme presumes
2 transmit (Tx) and arbitrary number of receive (Rx) elements.
If Rx=1 (one receive element) ALAMOUTI is transformed to the order 2
transmit diversity scheme with Maximum Ratio Combining (MRC). The
modulation format is MPSK with arbitrary order M which can be
controlled by user.
