Web2.5.2 Pilot tone acquisition. The pilot tone is recorded in the oversampled region of the readout of the Fourier-transformed k-space data, as depicted in Figures 2A and 3. For each k-space line and coil, a complex signal is obtained at the readout position that corresponds to the PT frequency.

WebHow is a pilot tone found? The location of pilot tones in terms of sub-carriers is defined by the signal protocol. For instance, in the case of 802.11a the pilot sub-carriers are -21, -7, 7, and 21. What makes it different than the regular data on a sub-carrier? It is different in that the receiver knows exactly what the pilot tone contains. http://electronbunker.ca/eb/AM_StereoXMTR.html WebAug 7, 2024 · I am trying to use the frequency offset calibration for receivers code available in MATLAB to process a set of IQ data I received from a spectrum analyzer.
