Recursion is when a function calls itself . Recursive functions have always been tricky for me. When I was a lecturer, teaching recursive functions was both fun and annoying because most students were unable to understand it for the first time. The simplest way to understand the recursion is to…

(The following is for my own reference and has used materials partially from: https://devopedia.org/5g-nr-bandwidth-part) A Cellular Device (often known as UE) access to the network (e.g. after power ON) starts with acquiring the Synchronization Signal Block (SSB) that consists of 3 components: PSS, SSS and PBCH. SSB spans 4 OFDM…

Cellular data is carried over frequency resources (Subcarriers or SCs) transmitted over time-domain symbols. The combination of subcarrier and symbols is what makes the basis of the Resouce Grid (See Fig. 1). In 5G NR Resource Grid, we have several terminologies that are often quite confusing for beginners so I’ll…

The dataset that I am using can be downloaded from here in its raw format. However, for this code, I need cleaned data. Check my Git for the code and the cleaned and ready-to-use cleaned version of data. So let’s get started. 1. Load packages and data import numpy as np import pandas as pd import…

Simple steps to work with Git on Jupyter Lab/Notebook environment. — First, open the terminal for Anaconda or Miniconda (I use Miniconda for myself). Then in the environment of your choice install the jupyterlab-git package (I did it in the Base environment). Note that you will only be able to use JupyterLab Git in the environment where you have installed it…

How does a UE decode Downlink Control Information (DCI) in 5G NR? Downlink Control Information (DCI) carries information from gNB-to-UE such as info DL/UL resource scheduling, power control, modulation and coding schemes to decode a message, HARQ related aspects etc. A DCI is carried as a payload within Physical Downlink…

Disclaimer: I am only an expert in Telecom/5G and do not possess medical or neurological expertise beyond what any logical non-expert would have. The short answer to the concern: No Reason: The real magic in the 5G can be categorised into two classes, Class 1: Over-the-Air Magic. Class 2: Magic…

Let’s write and understand a simple hello-world code for quantum computers using Qiskit — Like classical computers have bits with states ‘0’ or ‘1’, quantum computers have Quantum Bits (Qubits). In a Quantum computer, Quantum Bits (Qubits) are the fundamental units of information. They are the counterpart of bits used for classical computers with states 0 and 1. …

Time series forecasting methods take data from the past N values and predict the future values. In this article (keeping things simple) I present predictions of the cellular network’s future traffic using the past values. However, a reader can replace cellular traffic with any parameter of interest (e.g. …
