时变信道中 OFDM 信号的多 FFT 检测
多FFT解调可与相干或差动相干检测可以应用。差异相干检测可能对时变信道的优点,其中相干检测患有通道
估计误差。最好是在频域中执行的差分编码,即在整个OFDM载波。在可供下载的源代码包在http://millitsa.coe.neu.edu/?q=projects,多FFT解调与差分相干检测和多个接收元件(空间分集)来实现。

正交频分多路复用
正交频分复用 (OFDM) 是一种通信技术,通信信道分为同样间隔的频段的数目。副载波携带用户信息的一部分是在每个波段中传输。每个子载波与每一个其他副载波,从常用的频分复用 (FDM) 鉴别 OFDM 是正交 (相互独立)。频分复用 (FDM) 是一种技术,通过单一的传输路径如电缆调制解调器或无线系统同时传输多个信号。每个信号传播在其自身独特的频率范围内 (载波) 调制的数据 (文本、 语音、 视频等)。正交 FDM (OFDM) 扩频技术将数据分布在一大批以精确的频率间隔的载体。这种技术中的这个间距提供"正交"以防止解调器看到自己以外的其他频率。

在这个仿真模型,16
In this simulink model , 16-QAM 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
at the detector output.-In this simulink model , 16-QAM 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
