Figure 12: Now our Zero Padded DFT looks more like those other textbooks Fourier Transform Plots. A lot more detail is evident, but this technique does not add actual resolution because we did not add ...

The RF detector, a key element of a radio front-end DfT circuitry, designed in 65 nm CMOS is used to demonstrate the calibration scheme. Published in: 2008 IEEE Radio Frequency Integrated Circuits ...

In this paper, a delay calibration method of VLBI terminal device based on PCAL (Phase Calibration) signal is proposed. To solve the problem of low computational efficiency of PCAL signal extraction ...
