做OFDM通信少不了频谱分析，基带信号DA后的频谱，以及基带数字上变频后的DA信号都要频谱分析。我觉得实做任何工程都是这样，先规定实施方案，然后仿真成功，再实际开发，不过也可以一边开发，一边仿真，开发结果要与仿真预期结果一致。 所以分析与仿真 ...

The FFT (Fast Fourier Transform) is rightfully regarded as the most important numerical algorithm of our lifetime. Whether it's used to monitor signals coming from the depths of the earth or search ...
If you do any electronics work–especially digital signal processing–you probably know that any signal can be decomposed into a bunch of sine waves. Conversely, you can generate any signal by adding up ...
In January, four MIT researchers showed off a replacement for one of the most important algorithms in computer science. Dina Katabi, Haitham Hassanieh, Piotr Indyk, and Eric Price have created a ...
FFT-EM is an innovative method that represents a combination of FFT and EM techniques such as scanning electron microscopy (SEM). The technique is often used to determine the interior and surface ...
