“…David J. Young and Norman C. Beaulieu proposed a method in their paper titled ''The Generation of Correlated Rayleigh Random Variates by Inverse Discrete Fourier Transform'' [15] based on the inverse discrete Fourier transform (IDFT). It is a modification of the Smith's algorithm which is normally used for Rayleigh fading simulation.…”

The present paper analyzes the effect of LDPC coding on the performances of a CDMA DS-SS multiuser system. Two types of detectors are analyzed, namely the conventional matched filter and the MMSE ones, in the ideal case-when the spreading codes are perfectly orthogonal and in a non-ideal one-when the users are more or less intercorrelated. Regarding the communication channel, several cases have been taken into consideration, from pure AWGN or Gaussian Mixture Noise to Rayleigh and Rice fading with different parameters. A large number of simulations have been performed using the Monte Carlo technique and the results are summarized and compared in the final part. Based on those results a number of interesting conclusions are highlighted in the Conclusion section.

“…To our best knowledge, existing papers always consider the 2-D channel model [14,15], while the application of AR method in 3-D channel modeling is rarely introduced. Hence, both the 3-D channel model and AR method are investigated in our study.…”

This paper presents the application of autoregressive (AR) methods in 3-D fading channel modeling and generation. It employs the AR method to yield the filter coefficient in the 3D and non-isotropic scattering environment, and derives the channel statistics from the geometry-based stochastic channel model (GSCM). Simulations show that the statistical variable of simulated channel agrees with the referenced model. Moreover, by exploiting the Agilent advanced design systems (ADS) software and the Agilent E4432B vector signal generator, the above AR model can be realized in ADS, and then the physical fading channel can be generated through the E4432B instrument. The tests of frequency analyzer demonstrate that the proposed scheme can generate the physical fading channel precisely by the design requirement.
