Alamoutiwork
程序的主要功能是做了一定范围的信噪比下,对每个信噪比:随机信号QPSK调制;
根据Alamouti方案的矩阵进行编码;发送信号经过瑞利信道和加入高斯白噪声;
接收信号采用最大比合并的方法;最后对合并信号进行最大似然判决并求误符号率。
结果表明10^-3对应大约12->13dB(Procedure main function is to do a certain range of SNR for each signal to noise ratio: random signal QPSK modulation program in accordance with Alamouti coding matrix send signals through Rayleigh channel and adding Gaussian white noise received signal using maximal-ratio combining method Finally the combined signal and the maximum likelihood decision for symbol error rate. The results showed that about 10 ^-3 corresponds to 12-> 13dB)

Fourier-transform
傅 立叶变换是数字信号处理领域一种很重要的算法。要知道傅立叶变换算法的
意义,首先要了解傅立叶原理的意义。傅立叶原理表明:任何连续测量的时序或
信号,都 可以表示为不同频率的正弦波信号的无限叠加。而根据该原理创立的
傅立叶变换算法利用直接测量到的原始信号,以累加方式来计算该信号中不同正
弦波信号的频 率、振幅和相位。 (The goals for the course are to gain a facility with using the Fourier transform, both specific techniques and general principles, and learning to recognize when, why, and how it is used. Together with a great variety, the subject also has a great coherence, and the hope is students come to appreciate both. )
