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 multiple …

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 along with …

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 Symbol …

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 the RA …

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 contention-driven …
