An exact solution for the level-crossing rate and the average duration of fades of the envelope of sum-of-cisoids processes
Pätzold, Matthias; Castillo, Javier Vázquez; Gutiérrez, Carlos A.; Michel, Ramón Parra (Journal article; Peer reviewed, 2012)Sum-of-cisoids (SOC) processes provide a physically and numerically appealing framework for the modelling and simulation of a wide class of mobile radio channels. This paper is concerned with the problem of finding a general ... -
Channel simulation models for mobile broadband communication systems
Gutiérrez, Carlos A. (Doctoral thesis; Peer reviewed, 2009)Mobile broadband wireless communication systems (MBWCS) are emerging as a solution to provide broadband services to users on the move. These systems are expected to operate in a wide variety of propagation scenarios, at ... -

Classes of sum-of-cisoids processes and their statistics for the modeling and simulation of mobile fading channels
Hogstad, Bjørn Olav; Gutiérrez, Carlos A.; Pätzold, Matthias; Crespo, Pedro M. (Journal article; Peer reviewed, 2013)In this paper, we present a fundamental study on the stationarity and ergodicity of eight classes of sum-of-cisoids (SOC) processes for the modeling and simulation of frequency-nonselective mobile Rayleigh fading channels. ... -
The Design of Sum-of-Cisoids Rayleigh Fading Channel Simulators Assuming Non-Isotropic Scattering Conditions
Gutiérrez, Carlos A.; Pätzold, Matthias (Journal article; Peer reviewed, 2010)n this letter, we introduce the Riemann sum method (RSM) as an effective tool for the design of sum-of-cisoids (SOC) simulators for narrowband mobile Rayleigh fading channels under non-isotropic scattering conditions. We ... -
On the correlation and ergodic properties of the squared envelope of SOC Rayleigh fading channel simulators
Gutiérrez, Carlos A.; Pätzold, Matthias (Journal article; Peer reviewed, 2012)In this paper, we investigate the correlation and ergodic properties of the squared envelope of a class of autocorrelation-ergodic (AE) sum-of-cisoids (SOC) simulation models for mobile Rayleigh fading channels. Novel ... -
On the problems of symbol-spaced tapped-delay-line models for WSSUS channels
Gutiérrez, Carlos A.; Cabrera-Bean, Margarita; Pätzold, Matthias (Peer reviewed; Journal article, 2009)This paper analyzes the validity and statistical behavior of symbol-spaced tapped-delay-line (SSTDL) models for wide-sense stationary uncorrelated scattering (WSSUS) mobile radio channels. SSTDL models are obtained by ... -
