OFDM 传输的一种新的组合脉冲噪声缓解方案研究
摘要-Impulsive噪音缓解了正交频分复用（OFDM）可以使用两个阈值剪贴归零方案来完成。我们引入一个新的结合脉冲噪声消除方法，称为clippingreplacement-归零计划，其中有三个考虑阈值：限幅阈Tclip，更换门槛TREP和归零门槛Tnull。当接收到的OFDM样本的幅度高于TREP和下方Tnull我们将其设置为所述平均幅度JX？无噪声的OFDM样本第j。模拟结果表明，附加的动作，替换动作，与TREP的一个很好的选择带来在误码率的降低。

FFT的C++代码及TeeChart画图
采用VS2010平台实现了FFT变换，其中采用原位运算方式，精度为浮点（运算量和精度的折中）。利用指针传递参数，输入和输出为同一数组，包含实部和虚部。画图部分用于显示运算结果。从图像显示的计算结果来看，FFT运算结果正确。

In this simulink model , BPSK modulation and demodulation is simulated .A square root raised cosine pulse shaped signal is modulated and given as input to the demodulator.The received signal
is demodulated and given to the detector where it is matched filtered and down-sampled .The effects of symbol timing offset
can be seen by varying the phase of down-sampling
operation.The signal transmitted is recovered
