With the advent of multimedia, digital signal processing (DSP) of sound has emerged from the shadow of bandwidth-limited speech processing. Today, the main appli- cations of audio DSP are high quality audio coding and the digital generation and manipulation of music signals. They share common research topics including percep- tual measurement techniques and analysis/synthesis methods. Smaller but nonetheless very important topics are hearing aids using signal processing technology and hardware architectures for digital signal processing of audio. In all these areas the last decade has seen a significant amount of application oriented research.

OFDM的一种频分复用方案。把频谱分成两个部分，一部分频谱用同频复用，一部分频谱采用复用因子为3，这就是reuse partitioning,或者叫部分频率复用技术（Fractional Frequency Reuse)。频率复用因子表示一个频率复用簇当中的频点的数量。复用因子越大，表示复用距离越大。代码对FFR进行了仿真，适合初学者。
