WebOFDM and OFDMA look quite similar from an initialism [1] standpoint, but in fact are used very differently in DOCSIS 3.1 and 4.0. OFDM is used in the downstream and is a common channel shared by all compatible cable modems. OFDMA is used in the upstream by cable modems transmitting data to the CMTS. OFDMA is a time- and frequency-shared … WebJun 4, 2024 · Orthogonal Frequency Division Multiple Access (OFDMA) is a further enhancement to OFDM that lets multiple devices share a wireless channel, improving the channel’s overall use. OFDMA is already deployed in 4G and 5G. In the world of wireless LAN, the latest Wi-Fi standard ( IEEE 802.11ax) uses OFDMA for both uplink and …

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 …
