用charal函数实现对加噪降晰图像的反降晰.charal函数实现约束最小二乘法的算法，其中alpha（1/lamda）由Charalambous确定.反降晰的图像相对于降晰加噪图像清晰度有所提升，但是反降晰的图像存在较为明显的寄生波纹。(Deblurring the blurred image with noise by using Charal function. Charal function implements constrained least squares algorithm, where alpha (1/lamda) is determined by Charalambous. Compared to the blurred image, the sharpness of the image deblurred has improved, but obvious parasitic ripples arise.)

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.
