Spectrum sensing and awareness are challenging requirements in cognitive radio (CR). To
adequately adapt to the changing radio environment, it is necessary for the CR to detect the …

The emerging trend to provide users with ubiquitous seamless wireless access leads to the
development of multi-mode terminals able to smartly switch between heterogeneous …

The detection of orthogonal frequency division multiplexing (OFDM) for cognitive radio is
considered in this paper. A frequency-selective fading channel is considered and the …

This paper investigates the second-order cyclostationarity of block transmitted-single carrier
linearly digitally modulated (BT-SCLD) signals, and its applications to signal classification …

In this paper, a distinctive cyclostationarity-based feature of the Long Term Evolution (LTE)
Orthogonal Frequency Division Multiplexing (OFDM) signals used in the Frequency Division …

Cyclostationary analysis is a powerful tool to study the Signal-Selective Direction Estimation
(SSDE) problem as different types of wireless signals have different cyclostationary patterns …

We propose a novel approach to joint sensing and communications based on the use of
spectrally sparse sensing waveforms combined with standard communications signals …

Spectrum sensing of orthogonal frequency division multiplex (OFDM) system has always
been a challenge in cognitive radios (CR), especially for users which utilize the full-duplex …

The recent evolution of digital communication systems (voice, data and video) has been
dramatic. The 3GPP Long Term Evolution (LTE) system is one of the latest developments in …

Spectrum sensing of orthogonal frequency division multiplex (OFDM) system has always
