OFDMA Channel Equalization – Pilots OFDMA systems can have wideband channels – how do we equalize the channel?

Abstract—Orthogonal Frequency-Division Multiple Access (OFDMA) is a feature implemented in IEEE 802.11ax (Wi-Fi 6) that aims to improve performance by sending packets simultaneously …

To design and implementation of the OFDMA for the eNodeB architecture using the modeling tool and then perform the embedded design and implementation with ARM Cortex-A53 Quad Core …

The Main Objective is to design and validate a FFT Window Positioning based OFDMA system as replacement to the conventional OFDMA system in order to minimize the narrow band Inter …

We use pure UL OFDMA to illustrate the performance of UL OFDMA without the effect of the full bandwidth transmissions. In this case, unscheduled stations are only allowed to contend for …

OFDMA brings an improvement over prior versions of Wi-Fi that use orthogonal frequency division multiplexing (OFDM). It subdivides the Wi-Fi channel into smaller frequency allocations called …

In this study, we validate the implementation of 802.11ax OFDMA in the ns-3 simulator by comparing simulation results obtained from ns-3 with those predicted by an analytical model in …
