Discrete Rayleigh fading channel modeling [PDF]
Wireless Communications and Mobile Computing, 2004 AbstractIn order to understand the behaviour of upper‐layer protocols and to design or fine tune their parameters over wireless networks, it is common to assume that the underlying channel is a flat Rayleigh fading channel. Such channels are commonly modeled as finite state Markov chains.

MLSE receiver for the dispersive Rayleigh fading channel [PDF]
Proceedings of ICC'97 - International Conference on Communications, 2002 A maximum likelihood sequence estimator for the dispersive Rayleigh fading channel is developed. Following [1, 2], the MLSE uses a Kalman based channel estimator to acquire the channel parameters necessary to formulate the maximum likelihood metric. However, unlike the MLSE receiver presented in [1, 2], the proposed receiver uses the f-power series ...

Adaptive modulation in a slow Rayleigh fading channel [PDF]
Proceedings of PIMRC '96 - 7th International Symposium on Personal, Indoor, and Mobile Communications, 2002 A novel, uneven protection phase shift keying technique is proposed for the encoding of the required modulation scheme in an adaptive modem arrangement, which exhibits an improved performance in comparison to previously proposed schemes. The performance is derived numerically and a system dependent optimisation is presented.

The Slashed‐Rayleigh Fading Channel Distribution
Mathematical Problems in Engineering, 2019 We propose an alternative distribution for modelling fading‐shadowing wireless channels. This distribution presents certain advantages over the Rayleigh‐lognormal distribution and the K distribution and has proved useful in the setting described. We obtain closed‐form expressions for the average channel capacity and for the average bit error rate of ...

Effective capacity of a correlated Rayleigh fading channel [PDF]
Wireless Communications and Mobile Computing, 2011 AbstractThe next generation wireless networks call for quality of service (QoS) support. The effective capacity (EC) proposed by Wu and Negi provides a powerful tool for the design of QoS provisioning mechanisms. In their previous work, Wu and Negi derived a formula for effective capacity of a Rayleigh fading channel with arbitrary Doppler spectrum ...

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.

Multiuser diversity in correlated Rayleigh-fading channels [PDF]
EURASIP Journal on Wireless Communications and Networking, 2012 This article studies the effect of scheduling and multiuser diversity on the performance of correlated Rayleigh-fading channels. More specifically, the power-limited channel average rate is obtained for quasi-static correlated fading channels. The results are obtained in the cases where there is perfect or imperfect channel state information available ...

Journal of King Saud University: Computer and Information Sciences, 2016 In this paper we evaluate the performance of cooperative spectrum sensing (CSS) where each cognitive radio (CR) employs an improved energy detector (IED) with multiple antennas and uses selection combining (SC) for detecting the primary user (PU) in ...
