LEON over 4 years ago 0 Hari Nagalla over 4 years ago WebIn telecommunications, in-band signaling is the sending of control information within the same band or channel used for data such as voice or video. This is in contrast to out-of-band signaling which is sent over a different channel, or even over a separate network. WebFrequency correction. Shift the received waveform in frequency to bring the NB-IoT spectrum to baseband (0 Hz). Filter out the LTE component and downsample. Downsample the waveform to the NB-IoT sampling rate and filter out the frequencies outside the NB-IoT band. Time synchronization.
