The differences in Operating Frequencies & Bandwidth (4G vs. 5G):

We know that these 4G LTE operational frequency was between a few huna hundred 4 GHz. However, in the case of 5G, extremely high frequencies (EHF) or millimeter wave frequencies will be used. The 5G spectrum spans 26 to 100 GHz. However, in some countries, 5G is now based at frequencies below 6 GHz or sub 6 GHz (or below 6 GHz band).


The possible peak bandwidth for 5G will be several gigahertz, which is significantly more than the bandwidth available for 4G.


MIMO in 4G LTE v/s Massive MIMO in 5G:

MIMO technology was employed in 4G LTE; however, in 5G, massive MIMO technology is used for faster data rates and better spectral efficiency. Massive MIMO is useful for spatial multiplexing and narrow beam production. A narrow beam can cover more distance with the same energy than a wider beam.


Cell concept in 4G v/s 5G:

When addressing 5G, we must consider network densification. We shall discuss ultra-dense networks in this article. Because 5G has an extensive spectrum resource and the number of connected devices is rapidly growing, it fulfills the demands. 5G can support thousands of devices per square kilometer wh, ere 4G can connect hundreds of devices. In compComparedLTE, 5G cell coverage will be limited. It is also known as a 5G microcell.

Power Spectral Density Calculation Using FFT in MATLAB

📘 Overview 🧮 Steps to calculate the PSD of a signal 🧮 MATLAB Codes 📚 Further Reading Power spectral density (PSD) tells us how the power of a signal is distributed across different frequency components, whereas Fourier Magnitude gives you the amplitude (or strength) of each frequency component in the signal. Steps to calculate the PSD of a signal Firstly, calculate the fast Fourier transform (FFT) of a signal. Then, calculate the Fourier magnitude (absolute value) of the signal. Square the Fourier magnitude to get the power spectrum. To calculate the Power Spectral Density (PSD), divide the squared magnitude by the product of the sampling frequency (fs) and the total number of samples (N). Formula: PSD = |FFT|^2 / (fs * N) Sampling frequency (fs): The rate at which the continuous-time signal is sampled (in ...

ASK, FSK, and PSK (with MATLAB + Online Simulator)

📘 ASK Theory 📘 FSK Theory 📘 PSK Theory 📊 Comparison 🧮 MATLAB Codes 🎮 Simulator ASK or OFF ON Keying ASK is a simple (less complex) Digital Modulation Scheme where we vary the modulation signal's amplitude or voltage by the message signal's amplitude or voltage. We select two levels (two different voltage levels) for transmitting modulated message signals. Example: "+5 Volt" (upper level) and "0 Volt" (lower level). To transmit binary bit "1", the transmitter sends "+5 Volts", and for bit "0", it sends no power. The receiver uses filters to detect whether a binary "1" or "0" was transmitted.

OFDM vs SC-OFDM

  The main difference between OFDM and SC-OFDM is that SC-OFDM transmits the signal using a single carrier, while OFDM uses multiple subcarriers. However, in SC-OFDM, the signal is generated with different sub-bands, but it is transmitted through a single carrier (more technically, through a wideband carrier signal). Block Diagram of OFDM: Data → Modulation → Serial-to-Parallel → IFFT → Add CP → Transmit Received Signal → Remove CP → FFT → Parallel-to-Serial → Demodulation → Data Block Diagram of SC-OFDM: Data → Modulation → DFT → IFFT → Add CP → Transmit Received Signal → Remove CP → FFT → Demodulation → Data    In the case of OFDM, the input modulated data is converted from a serial stream to parallel streams, and different subcarriers are assigned to each chunk. Then, IFFT is applied to these chunks, and a cyclic prefix is added to each one. Each chunk is technically referred to as an OFDM symbol . Unlike OFDM, SC-OFDM does not perform serial-to-parallel conversion o...
