Evaluation of the Capabilities of LDPC Codes for Network Applications in the 802.11ax Standard

The use of Wi-Fi-enabled devices is increasing every year. Current consumer demands are related to the requirements for greater rate, greater reliability and greater energy efficiency. In the proposed chapter, studies of signal code construction (SCC) used in Wi-Fi standards: 802.11ac and 802.11ax were carried out. Aspects of beamforming and the use of LDPC codes in robust implementations are described. The relevance of the work is to create recommendations for the use of LDPC and their implementation using the hardware description language (HDL). The chapter focuses on the concept of building an LDPC decoder within the Norm-Min-Sum algorithm in HDL. Recommendations for the efficient use of LDPC-based SCC for 802.11 applications are presented. LDPC codes are popular because they have very good performance and allow for simple hardware implementations. The proposed results will be useful for optimizing signal selection for modern network applications.
