Carrier-frequency offset (CFO) estimation for uplink orthogonal frequency-division
multiplexing access (OFDMA) systems is very challenging as it requires the estimation of …

In this survey, we analyze the newest machine learning (ML) techniques applied in modern
optical orthogonal frequency division multiplexing (O‐OFDM) systems for access, core …

This paper analyses a scenario where a Device-To-Device (D2D) pair coexists with an
Orthogonal Frequency Division Multiplexing (OFDM) based incumbent network. D2D …

In this article, we show that the non-ideal Radio-Frequency (RF) front-ends have to be
corrected in order to contribute in a Green radio development. In fact, the effects of typical RF …

In this paper, we study the BER performance of Multi-Band Orthogonal Frequency Division
Multiplexing Ultra Wideband (MB-OFDM UWB) systems with frequency synchronization …

In this paper, we propose a joint estimation method of carrier frequency offsets (CFO) and
channel impulse responses (CIR) for an uplink OFDMA system. We consider the CFOs come …

In this paper, we investigate the effect of subcarrier allocation on the CFO for uplink OFDMA
systems. Carriers are allocated to the users in order to get maximum throughput by making …

In OFDMA, the total available subcarriers are assigned to different users for simultaneous
transmission. In case of an unsynchronized uplink OFDMA, each user has a different carrier …
