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)-The main function Alamouti (Nr, max_snr, max_err_symbol, symbol_per_frame) function call QpskMapping (psudo_bit_sequence)- binary data to the QPSK signal transformation function call RayleighCH (Nr, Nt)- Rayleigh fading channel Simulation Example: Alamouti (1,12 , 20,24) Description: 1.2 transmission antennas, a receiving antenna 2. the highest SNR 12dB, that is, simulation range of 0dB to 12dB 3. in each signal to noise ratio conditions, the misuse of symbols that stop a few more than 20 The signal to noise ratio under the conditions of simulation 4. each frame of data for the 24 QPSK symbols integrated simulation function SimAlamouti (max_snr, max_err_symbol, symbol_per_frame) with a receiving antenna system SER performance and two receive antenna system SER performance comparison SimAlamouti (12,20,24)

Description: 这个程序除了接收机同步、信道编码没有加入外，基本上反映了一个OFDM系统的特性：
1. qpsk/16qam/64qam映射、解映射
2. OFDM调制解调（循环前缀，FFT等）
3. 非整数采样时刻多径时延的多径信道
4. Rayleigh或者Rician多径信道
5. 信道的连续时变（非block fading）
6. 线性插值信道估计
7. FFT变换域插值信道估计-In addition to this program receiver synchronization, channel coding have not joined, the basically reflect the characteristics of an OFDM system: 1. Qpsk/16qam/64qam mapping, mapping solution 2. OFDM modulation and demodulation (cyclic prefix, FFT, etc.) 3. Non- integer sampling instant multi-path delay of multi-path channel 4. Rayleigh or Rician multipath channel 5. a continuous time-varying channel (non-block fading) 6. linear interpolation channel estimation 7. FFT transform domain interpolation channel estimation
