Compensating for Channel Fading in DS-CDMA Communication Systems Employing ICA Neural Network Detectors [PDF]
Journal of Systemics, Cybernetics and Informatics, 2005 In this paper we examine the impact of channel fading on the bit error rate of a DS-CDMA communication system. The system employs detectors that incorporate neural networks effecting methods of independent component analysis (ICA), subspace estimation of

Degrees of Freedom of Generic Block-Fading MIMO Channels without A Priori Channel State Information
, 2014 We studynthe high-SNR capacity of generic MIMO Rayleigh block-fading channels in the noncoherent setting where neither transmitter nor receiver has a priori channel state information but both are aware of the channel statistics.

Generic Correlation Increases Noncoherent MIMO Capacity [PDF]
, 2013 We study the high-SNR capacity of MIMO Rayleigh block-fading channels in the noncoherent setting where neither transmitter nor receiver has a priori channel state information. We show that when the number of receive antennas is sufficiently large and the

Instantaneous Capacity of OFDM on Rayleigh-Fading Channels [PDF]
IEEE Transactions on Information Theory, 2007 For a power limited orthogonal frequency-division multiplexing (OFDM) system transmitting a large number N of subcarriers over a Rayleigh-fading channel, the distribution of the instantaneous capacity is shown to be approximately Gaussian. The mean and variance of the approximating distribution are derived.

On the MIMO Capacity for Distributed System under Composite Rayleigh/Rician Fading and Shadowing
International Journal of Antennas and Propagation, 2015 Wireless channels are commonly affected by short-term fading and long-term fading (shadowing). The shadowing effects must be taken into account also when mobility is present in the wireless scenario.
