Optical Orthogonal frequency division multiplexing (OOFDM) is shown to outperform RZ-
OOK transmission in high-speed optical communications systems in terms of transmission …

The possibility of 100-Gb/s transmission over 25-GHz bandwidth using orthogonal frequency-
division multiplexing (OFDM) is demonstrated. It is shown that 100-Gb/s transmission over …

The IEEE 802.16 standard, also known as WiMAX is oriented to fixed broadband wireless
metropolitan access. This work presents a novel proposal for the PHY layer and propagation …

An analog/mixed-signal (AMS) Fourier transform circuit topology is presented that has the
potential to significantly reduce power consumption in future broad-band OFDM systems …

In this paper, we propose P-SLM (partitioned-selective mapping) scheme with low
complexity for PAPR (peak-to-average power ratio) reduction of OFDM (orthogonal …

In this paper, we present a method for estimating the Doppler spread (DS) in Wireless Local

In this contribution we propose a hybrid MQAM/LFSK modulation (HQFM) scheme and
showed its performance over Rayleigh fading channels using different modulation formats …

In order to improve OFDM (orthogonal frequency division multiplexing) PAPR (peak-to-
