Reducing transmit power is the most straightforward way towards more energy-efficient
communications, but it results in lower SNRs at the receiver which can add a performance …

Analog to digital transition in broadcasting systems enables efficient use of the frequency
spectrum and high-quality broadcast services. Many countries have adopted a digital radio …

Abstract Orthogonal Frequency Division Multiple Access (OFDMA) is among the promising
candidates for future generation of wireless communications, due to its robustness to …

Currently digitalization of analog broadcasting systems is taking place because digital
broadcasting has many advantages such as efficient use of the frequency spectrum and …

Nowadays, communication systems are usually implemented by digital modulated
waveforms. Such is the case of OFDM, where the spectrum efficiency and the robustness …

OFDM is a promising high-speed data transmission platform, and wireless OFDM LAN/MAN
has rapidly developed since some OFDM network technologies were standardized. In this …

In this paper, the effects of residual frequency offset on OFDM systems are analyzed, and
incorrect decision will be made due to the introduced signal constellation rotation …

In this paper, we propose an iterative detection scheme in the presence of residual
frequency offset (RFO) for orthogonal frequency-division multiplexing (OFDM) system using …

Abstract Device-to-device (D2D) networking enables direct discovery and communication
between cellular subscribers that are in proximity, thus bypassing the base stations (BSs). In …

In this report, proper frequency sub-band assignment and frequency guard band (GB)
allocation is used to mitigate the effect of Multiple Access Interference (MAI), caused by …
