On the performance of subcarrier allocation techniques for multiuser OFDM cognitive networks with reconfigurable antennas
(Institute of Electrical and Electronics Engineers Inc., 2014)
Reconfigurable antennas (RA) have been viewed as a hardware-efficient alternative solution to multiple-input multiple-output systems whereby network users can vary the antenna radiation patterns using a single antenna ...
Clipping noise mitigation using partial transmit sequence for optical OFDM systems
(Institute of Electrical and Electronics Engineers Inc., 2014)
Orthogonal frequency division multiplexing (OFDM) is a promising technology to achieve higher data rates in optical wireless communication (OWC) systems. Unlike single carrier techniques, OFDM can easily handle inter-symbol ...

Fm channel model development and its emulator
(Institute of Electrical and Electronics Engineers Inc., 2018)
With the widespread availability of Internet, voice only broadcast in the FM Band will soon be abandoned as Internet Radio can provide the same content with no boundaries. The available band can then be exploited for ...
Low complexity peak-to-average power ratio reduction in OFDM-IM
(Institute of Electrical and Electronics Engineers Inc., 2018)
Orthogonal frequency division multiplexing with index modulation (OFDM-IM) employs the indices of the active subcarriers for information transmission, as an alternative to conventional OFDM. It offers high spectral efficiency ...
Reduced-rank joint estimation of DOA with mutual coupling
(Institute of Electrical and Electronics Engineers Inc., 2018)
In this paper, an extended reduced-rank direction-of-arrival (DOA) estimation with unknown mutual coupling in uniform linear array (ULA) structure is presented. The proposed method is based on the joint iterative subspace ...
A European view on the next generation optical wireless communication standard
