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.

说明：  MATLAB提供了多种方式从磁盘读入文件或将数据输入到工作空间，即读取数据，又叫导入数据；将工作空间的变量存储到磁盘文件中称为存写数据，又叫导出数据。(MATLAB provides a variety of ways from the disk is read into a document or data entered into the work space, that is, read data, also known as import data will work variable storage space to keep the disk file is called to write data, also known as export data .)
