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.

Phase vocoder is aprogram that allow you perform the shiftting pich without chort o long the time, using a factor value to do that

基于matlab/simulink搭建的三电平逆变器仿真模型，控制算法为电压空间矢量控制（SVPWM），算法部分使用m语言编写，带有简单注释，配合算法说明，应该比较好懂。模型带中点电压平衡处理，但是效果一般，大家可以在此模型基础上修改。欢迎交流讨论。(Three-level inverter simulation model matlab/simulink structures based control algorithms for the voltage space vector control (SVPWM), part of the algorithm using the m language, with a simple comment, with the algorithm description, it should be relatively easy to understand. Models with the midpoint voltage balanced, but the general effect, you can modify the model basis. Welcome exchanges and discussions.)
