Non-Causal IIR Filter Part 1: Setting up the Input signal to the Wiener Filter Part 2: Seperating the negative lags and positive lags... The one at 0 index is clustered together in the positive part highqq

qr分解的c语言程序,可以嵌入matlab使用(simulated decomposition of the c language program, can be embedded using Matlab)

this codes about ga and contain 8 codes

说明：  4. 试说明卷积编解码的工作原理： (1) 使用Simulink仿真卷积编码，并用Viterbi译码的方法进行解码，其中的编码、译码全部是自己编写代码(S-Function方式)，不是调用Simulink的已有编码、译码函数。 (2) 请在加性白高斯噪声信道中，画出比特信噪比与误码率的关系曲线。(4. Try to explain the working principle of convolutional codec: (1) Simulink was used to simulate convolutional coding, and Viterbi decoding method was used for decoding. The coding and decoding were all written by oneself (s-function method), rather than calling the existing coding and decoding functions of Simulink. (2) in the additive white gaussian noise channel, please draw the curve of the relationship between bit signal-to-noise ratio and bit error rate.)

说明：  产生BPSK信号，使用能量检测求检测概率； 对信号和噪声进行非负矩阵分解实现信号增强，和信号压缩(BPSK signal is generated by this code and ED is used to detect and calculate the detection probability.Finally, NMF method is used to enhance the signal.)
