Spectrum Sensing for Cognitive Radios With Unknown Noise Variance and Time-variant Fading Channels
IEEE Access, 2017 The unknown noise variance and time-variant fading channels make the spectrum sensing design a challenging task for cognitive radios. Most existing sensing methods suffer from the information uncertainty and can hardly acquire promising performances in ...

On the Secrecy Capacity of Fading Channels [PDF]
2007 IEEE International Symposium on Information Theory, 2007 We consider the secure transmission of information over an ergodic fading channel in the presence of an eavesdropper. Our eavesdropper can be viewed as the wireless counterpart of Wyner's wiretapper. The secrecy capacity of such a system is characterized under the assumption of asymptotically long coherence intervals. We first consider the full Channel

Rayleigh Fading Multi-Antenna Channels
EURASIP Journal on Advances in Signal Processing, 2002 Information theoretic properties of flat fading channels with multiple antennas are investigated. Perfect channel knowledge at the receiver is assumed. Expressions for maximum information rates and outage probabilities are derived.

Information Rates for Channels with Fading, Side Information and Adaptive Codewords
Entropy, 2023 Generalized mutual information (GMI) is used to compute achievable rates for fading channels with various types of channel state information at the transmitter (CSIT) and receiver (CSIR).

On multipath fading channels at high SNR [PDF]
2008 IEEE International Symposium on Information Theory, 2008 This paper studies the capacity of discrete-time multipath fading channels. It is assumed that the number of paths is finite, i.e., that the channel output is influenced by the present and by the L previous channel inputs. A noncoherent channel model is considered where neither transmitter nor receiver are cognizant of the fading's realization, but ...

Binary Fading Interference Channel with No CSIT [PDF]
2014 IEEE International Symposium on Information Theory, 2014 We study the capacity region of the two-user Binary Fading (or Erasure) Interference Channel where the transmitters have no knowledge of the channel state information. We develop new inner-bounds and outer-bounds for this problem. We identify three regimes based on the channel parameters: weak, moderate, and strong interference regimes.

Improved Pilot-Aided Channel Estimation for MIMO-OFDM Fading Channels
International Journal of Antennas and Propagation, 2013 An improved pilot-aided channel estimation scheme is proposed to enhance the channel estimation accuracy of multiple-input multiple-output-orthogonal frequency division multiplexing (MIMO-OFDM) fading channels. Based on the adaptive path number selection
