WebThe method proceeds by identifying a preamble of the incoming signal, followed by extracting a reference waveform corresponding to the identified preamble. Afterwards, the extracted waveform is crosscorrelated with the incoming signal. For doing so, the channel profiler includes an autocorrelator for identifying the preamble of the incoming signal. WebJan 24, 2024 · fig.3. Step1: The eNB reserves a set of preambles for this purpose and assigns a preamble from this and sends to UE. Step 2: Since this entire process is controlled by the eNB there is no collision. The UE now sends back the response of Random-Access Preamble with the UE ID. Step 3: The eNB then sends Random Access response with the … marcotte furniture
