医学图像的读取,存储及旋转平移的MATLAB语句实现.(medical image read and transformation. )

把图像二值化的代码，阈值为求去红色篮球的，如果是其他颜色，只需要修改相关阈值即可。(The image binary code, the threshold is seeking to red basketball, if it is other colors, just change the threshold value can be related.)

The Interleaved Frequency Division Multiple Ac- cess (IFDMA) scheme is based on compression, repetition and subsequent user dependent frequency shift of a modulated signal. Multiple access is enabled by the assignment of overlapping but mutually orthogonal subcarriers to each user. In this paper it is shown that IFDMA can be regarded as unitary precoded OFDMA with interleaved subcarriers. On the other hand, IFDMA is shown to be a CDMA variant with frequency domain orthogonal signature sequences and chip interleaving. Thus, it combines the advantages of single and multi carrier transmission such as low peak to average power ratio, orthogonality of the signals of different users even for transmission over a time dispersive channel and low complexity. Simulation results show the good performance of coded IFDMA transmission over a mobile radio channel for different data rates.
