What modulation and coding methods are used in 5G technology to reduce latency and to increase data rates?

Orthogonal Frequency Division Multiplexing (OFDM) is an efficient modulation format used in modern wireless communication systems including 5G. OFDM combines the benefits of Quadrature Amplitude Modulation (QAM) and Frequency Division Multiplexing (FDM) to produce a high-data-rate communication system.

What coding is used in 5G?

To fulfill 5G communications requirements, we use LDPC and Polar codes for error correction. In 5G NR (New Radio) LDPC codes used for the data channel and control channel Polar Codes are used. We get high Coding gain for this code. It has several features such as high throughput, low power dissipation, and low latency.

How is latency reduced in 5G?

The current architecture is a device on a network connected to the cloud, a setup that has unexpected latency. This is changing now with 5G. Edge computing reduces latency because the processing happens closer to the user, eliminating the need to send the data to the cloud and back.

How does 5G increase productivity?

“Given how amazingly fast the Internet connection is, it will make work much more efficient.” According to some estimates, 5G technology, which will process data in gigabits per second rather than in megabits, will eventually be 100 times faster than existing 4G networks.

How is 5G modulated?

The waveform format of 5G NR is based on OFDM – CP-OFDM and DFT-s-OFDM with adaptive modulation including QPSK and 16QAM, 64QAM, 256QAM. One of the defining elements of any mobile communications system is the waveform used for the radio link in the radio access network.

What type of modulation is used in cell phones?

Most radio systems and handsets use FM analog modulation that occupies a 25-kHz channel.

What channel coding method is adopted on control channels of 5G air interface?

Two capacity-achieving channel coding schemes of low-density parity-check (LDPC) codes and polar codes have been adopted for 5G where the former is for user data and the latter is for control information.

How does MEC reduce latency?

By shifting the load of cloud computing to individual local servers, MEC helps reduce congestion on mobile networks and decrease latency, enhancing the quality of experience (QoE) for end users.

How does 5G help?

5G wireless technology is meant to deliver higher multi-Gbps peak data speeds, ultra low latency, more reliability, massive network capacity, increased availability, and a more uniform user experience to more users. Higher performance and improved efficiency empower new user experiences and connects new industries.

How will 5G change?

As 5G continues to expand, people are going to feel the impact of the 5G revolution. Designed to have faster speeds, larger capacity and reduced latency, 5G is expected to be the key for innovation in tomorrow’s future. In particular, increased speeds can open new opportunities in public safety and business.
