How are the frequencies of the OFDM signals assigned to each user in the cellular network system?
More specifically, the cellular network divides the frequency by the number of clusters and assigns it to the user, I wonder how the sub carriers of OFDM are divided in a single cell.
Homework Answers
In ofdm we are dividing the entire bandwidth by no. Of subcarriers. And the centre-frequency in each region (i.e. in small bandwidth) is nothing but sub carrier frequency. Now each messenge signal multiplied by sub carrier frequency. And we are sending the each messenge in each sub carrier frequency. This we are calling as a cell.

Q1 Marks: 40 A digital communication system has 96 analog telephone signals, each band limited to 4 kHz. The telephone signals are converted to digital binary data using Pulse Code Modulator (PCM) system, which use a uniform quantiser followed by an 8-bit encoder. The system uses two bits for synchronization. The digital binary data are then time-division multiplexed and transmitted over a single communication channel. Analyse the communication system by considering the following principles: (i) Determine the number of quantization...

Objective: Write a program that implements the Game of Life cellular automata system invented by John Conway. 1. Create two game grids of size at least 50x50. These grid cells can be either Boolean or integer. In the following, I’ll refer to these as gridOne and gridTwo. 2. Set all cells in both grids to false. 3. Start by initializing gridOne. Allow the user to specify two different ways of initializing the grid: 1) by specifying a pattern file to...

(b.) Huffman code is a way to encode information using variable-length binary strings to represent symbols depending on the frequency of each individual letter. Specifically, letters that appear more frequently can be encoded into strings of shorter lengths, while rarer letters can be turned into longer binary strings. On average, Huffman code is a more efficient way to encode a message as the number of bits in the output string will be shorter than if a fixed-length code was used....

Case One: Railroads Struggle to Implement Positive Train Control Positive train control (PTC) is a complex system designed to prevent the human errors that cause roughly 40 percent of train accidents, including train-to-train collisions, derailments caused by excess speed, train movement through track switches left in the wrong position, and unauthorized incursion into work zones. PTC uses wireless communications to relay visual and audible data to train crew members regarding when the train needs to be slowed or stopped. This...
