In recent years, Wi-Fi has become the ubiquitous technology in the world. How to improve the efficiency and the transmission data rate become an important issue nowadays. In this thesis, we investigate detail the latest technology in Wireless Local Area Network IEEE 802.11ax, which is Orthogonal Frequency Division Multiple Access (OFDMA) transmission system model. Understand the terminology used by the wireless network and reinterpret the optimization problem in wireless network field by using standard mathematical descriptions. Find out the relevant background knowledge about Wireless Local Area Network technology, how the system model actually applied in the real world, and use mathematics to express the narrative of engineering problems. People with a mathematical background can understand the system and do numerical simulations more easily.
