About Coding in 5G?

Hello,
The 5G modulation: PSK & QAM
A variety of different modulation formats are used for 5G technology.

Phase shift keying: 5G technology implements quadrature phase shift keying, QPSK as the lowest order modulation format. Although this will provide the slowest data throughput it will also provide the most robust link and as such it can be used when signal levels are low or when interference is high.

Another form of PSK called π/2BPSK is used in conjunction with DFT-s-OFDM on the up link.

Quadrature amplitude modulation: Quadrature amplitude modulation enables the data throughput to be increased. Formats used within 5G mobile communications system include 16QAM, 64QAM and 256QAM.

The higher the order of modulation, the greater the throughput, although the penalty is the noise resilience. Therefore 256AM is only used when link quality is good, and it reduces to 64QAM and then 16QAM etc, as the link deteriorates. It is a balance between data throughput and resilience.

Thanks

Hello, Al_amery.
The modulation methods used by 5G can be divided into two categories PSK（Phase-Shift keying) or QAM（Quadrature Amplitude Modulation）
Thanks!
