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.

DFTs-OFDM vs OFDM: Why DFT-Spread OFDM Reduces PAPR Effectively (with MATLAB Code)

Understanding PAPR in DFT-spread OFDM vs. Standard OFDM In modern wireless communications like 4G LTE and 5G NR, managing the Peak-to-Average Power Ratio (PAPR) is critical for hardware efficiency. While OFDM is the gold standard for high-speed data, its high PAPR poses significant challenges for mobile devices. This is where DFTs-OFDM (also known as SC-FDMA) comes in. DFT-spread OFDM (DFTs-OFDM) has lower Peak-to-Average Power Ratio (PAPR) because it "spreads" the data in the frequency domain before applying IFFT, making the time-domain signal behave more like a single-carrier signal rather than a multi-carrier one like OFDM. Deeper Explanation: Aspect OFDM DFTs-OFDM Signal Type Multi-carrier Single-carrier-like Process IFFT of QAM directly QAM → DFT → IFFT PAPR Level High (due to many...

OFDM Symbols and Subcarriers Explained

This article explains how OFDM (Orthogonal Frequency Division Multiplexing) symbols and subcarriers work. It covers modulation, mapping symbols to subcarriers, subcarrier frequency spacing, IFFT synthesis, cyclic prefix, and transmission. Step 1: Modulation First, modulate the input bitstream. For example, with 16-QAM , each group of 4 bits maps to one QAM symbol. Suppose we generate a sequence of QAM symbols: s0, s1, s2, s3, s4, s5, …, s63 Step 2: Mapping Symbols to Subcarriers Assume N sub = 8 subcarriers. Each OFDM symbol in the frequency domain contains 8 QAM symbols (one per subcarrier): Mapping (example) OFDM symbol 1 → s0, s1, s2, s3, s4, s5, s6, s7 OFDM symbol 2 → s8, s9, s10, s11, s12, s13, s14, s15 … OFDM sym...
