5G (fifth generation communication technology) commercial is accelerating, and the fastest spread is expected to be in the 2018 PyeongChang Winter Olympics.
As the leading giants, Huawei, Ericsson, Nokia & Alang, ZTE and other top four communication companies are not only fighting for the scene in the terminal experiments, but also the basic core solutions.
According to media reports, in the discussion of the 5G short-code scheme of the just-concluded 3GPP RAN1 87 conference, the Polar Code scheme, which is mainly promoted by China Huawei, became the 5G control channel eMBB scene coding scheme (signaling coding).
The data shows that coding and modulation are the most esoteric part of wireless communication technology and are known as the crown of communication technology. This time, the Polar code won the victory of the control channel short code (uplink and downlink), and achieved a historic breakout in the case where the uplink and downlink short codes of the data channel and the full-length code scheme both cost the US LDPC camp.
It is understood that the polarization code was first proposed by Professor Erdal Arikan of Bilken University in Turkey in 2008. It is the only channel coding that can theoretically prove to reach the Shannon limit and has practical linear complexity coding and decoding capabilities. technology.

1. The development of TD-LTE technology, China's communication technology has become one of the mainstream technologies in the world for the first time. However, its core long code encoding Turbo code and short code tail biting convolutional code are not original Chinese technologies.
2. The coding camp from 3G, 4G to 5G is mainly the LDPC represented by the United States, the European Turbo represented by France and the Polar of China.
3. Europe's Turbo 2.0 lost momentum in the 5G era and became the direct PK of LDPC and China's Polar.
4. LDPC is led by Qualcomm, and its supporters include Intel, Samsung, Nokia, Verizon and others.
Polar is led by Huawei and ZTE. Supporters include vivo, OPPO, Xiaomi, Alibaba, Lenovo, China Unicom, China Telecom, China Mobile, Datang Telecom, Spreadtrum, China Mobile Research Institute, Xinwei Communication, Coolpad and the other side of the strait.
