First, for finite-duration sequences, a rate conversion with the DFT-domain approach is discussed. Next, using the result, the extended OLA and OLS are proposed for infinite-duration sequences. Finally, the computation complexities of our proposed methods are shown 展开 ...
Perform term by term multiplication of the transformed signals Inverse transform the result to get back to the time domain For short convolutions (less than a hundred samples or so), method 1 is usually faster. However, for longer convolutions, method 2 is ultimately faster. This is because...
Then, specify the test control signal that must be connected to the test pins of the integrated clock-gating cells, and connect the test signals. There are two scenarios to connect the test pins of the clock-gating logic: •Set up observability logic prior to mapping: If the control signa...
By using the FFT algorithm to calculate the DFT, convolution via the frequency domain can be faster than directly convolving the time domain signals. The final result is the same; only the number of calculations has been changed by a more efficient algorithm. For this reason, FFT convolution ...

The special cases of CZT are zoom FFT and "scaled FFT" (not sure what that does). DFT is also a special case of CZT, so if you callczt(data)with the default options, it's an FFT, but faster for prime sizes because of Bluestein's algorithm, useful inresamplefor instance? (#3956)...

A communication system has a first device HOA that transmits an information symbol with a zero-padded suffix (ZPS) and a second device HOB that receives the information symbol with the zero-padded suffix. The second device HOB performs a Fourier transform on at least one sample of the informa...

该文将WOLA滤波器组引入信道化接收机,以信号的平移代替窗函数的平移,对加权、叠接、相加后的信号进行DFT变换,实现了多相DFT滤波器组的相同功能,又解除了抽取倍数与信道数目的约束关系,是多相DFT滤波器组的一种推广形式。 2) Filter banks 滤波器组
