WebFeb 27, 2024 · OFDMA is a multi-user version of the OFDM digital-modulation technology. In Wi-Fi 6 (802.11ax), OFDMA is one of the critical feature to improve network performance. Both OFDM and OFDMA split transmitted data into several small packets, to move small bits of information in a simple way. Furthermore, OFDMA subdivides a channel into smaller ... WebApr 11, 2024 · Orthogonal Frequency-Division Multiple-Access (OFDMA) is used in different recent wireless communication systems. However, it is susceptible to carrier frequency offset (CFO) which effects the orthogonality between subcarriers and causes inter-carrier interference (ICI) and multiple access interference (MAI).
WebAug 18, 2024 · Channel estimation scheme for OFDM modulated transmissions usually combines an initial block-pilot-assisted stage with a tracking one based on comb or … WebFor 5G systems, flexible use of both DFT-S-OFDMA and OFDMA is recommended. DFT-S-OFDMA provides a low PAP ratio, which means a more efficient power amplifier, and a higher average transmit power to provide better coverage and data rate, and lower battery consumption. Nevertheless, equalization is required in the frequency domain, which …
