Abstract:

Formulation of the problem. With the rapid development of multimedia equipment and the development of technology, ultra-high-quality equipment with a resolution of 3840 ×2160 (4K2K) pixels, such as ultra-high definition television projectors (UHDTV), has been developed. Most devices use high-definition multimedia interface (HDMI) lines as transmission media, which are expensive and have length limitations; therefore, wireless transmission is an ideal solution. Devices for augmented reality (AR) or virtual reality (VR), mirroring mobile device screens, etc. also, as a rule, wireless transmission is used. Thus, wireless data transmission with a frequency of 60 GHz plays an important role in the era of the fifth generation (5G), where special attention is paid to high transmission speed, large data volume and low latency.

Purpose. Development of a reconfigurable low-density parity decoder architecture with suitable hardware for IEEE 802.15.3c, 802.11g and 802.11ay standards.

Practical significance. The reconfigurable Low-Density Parity Decoder (LDPC) is designed with suitable hardware for use in three 60 GHz wireless transmission standards: IEEE 802.15.3c, 802.11g and 802.11ay. This architecture flexibly supports 12 types of parity check matrices. The switching network uses an architecture that allows universal switching between different inputs and provides low hardware complexity. The control node block uses a switchable reconfigurable 8/16/32 structure to match different string weights at different encoding rates and uses a minimum sum algorithm to simplify the procedure for finding the minimum value.
