目前的代码是一个matlab函数，它提供给定信号x[n]的短时傅立叶变换（stft）。该函数是matlab命令“光谱图”的一个替代项。功能输出为： 1）一个具有复杂stft系数的矩阵，该矩阵具有跨列时间和跨行频率； 2）频率矢量； 3）时间矢量。 为了阐明函数的用法，给出了一个示例。为了方便起见，输入和输出参数在函数的开头给出。(The present code is a Matlab function that provides a Short-Time Fourier Transform (STFT) of a given signal x[n]. The function is an alternative of the Matlab command spectrogram The output of the function is 1) a matrix with the complex STFT coefficients with time across the columns and frequency across the rows; 2) a frequency vector; 3) a time vector. An example is given in order to clarify the usage of the function. For convenience, the input and output arguments are given in the beginning of the function.)

The channel estimation algorithm is based on a subspace approach. The method works only for identifiable STBCs (excluding >=1-rate STBCs). See publication [1] for more detail about the algorithm and the identifiability conditions. The zip file contains three m files. - space_time_coding.m (perform space time coding) - subspace_channel_estimation_STBC.m (channel estimation) - one_shot.m (show an example) To use these files, extract the three files in the same folder. Then, call the script one_shot in the matlab command window. Reference: [1] Ammar, N. Ding, Z.
