“…Reference [26] reported outstanding agreement between results obtained from one implementation of the Pop-Beaulieu simulator and theory in some turbo decoding applications. However, in general, the quality required of a simulator will depend on the application and some higher-order behaviors may not be accurately modeled using this simulator.…”

“…They proposed a Clarke's model-based simulator design having the WSS property in [19], [21]. The Pop-Beaulieu simulator has been employed in a number of diverse applications [26]- [29]. In the first part of this paper, we give a statistical analysis of Clarke's model with a finite number of sinusoids and show that the PopBeaulieu simulator has deficiencies in some of its higher-order statistics (as warned in [19,Section III.B]).…”

The statistical properties of Clarke's fading model with a finite number of sinusoids are analyzed, and an improved reference model is proposed for the simulation of Rayleigh fading channels. A novel statistical simulation model for Rician fading channels is examined. The new Rician fading simulation model employs a zero-mean stochastic sinusoid as the specular (line-ofsight) component, in contrast to existing Rician fading simulators that utilize a non-zero deterministic specular component. The statistical properties of the proposed Rician fading simulation model are analyzed in detail. It is shown that the probability density function of the Rician fading phase is not only independent of time but also uniformly distributed over [−π, π). This property is different from that of existing Rician fading simulators. The statistical properties of the new simulators are confirmed by extensive simulation results, showing good agreement with theoretical analysis in all cases. An explicit formula for the level-crossing rate is derived for general Rician fading when the specular component has non-zero Doppler frequency.

“…This choice has been made since the uniform interleaver approach has been applied to design the puncturing patterns: thus, the optimality of a given pattern is not specific to a particular interleaving scheme, but to the optimality of the average distance spectrum of the code obtained, applying that pattern. Thus, the simulation is not performed using a specific interleaving scheme but a random interleaver, yielding also a better closeness of simulation results to the union bound [15]. Moreover, since we are interested in the comparison of the three criteria considered, a short interleaver length, such as 100, has been considered.…”

We propose and compare some design criteria for the search of good systematic rate-compatible punctured turbo code (RCPTC) families. The considerations presented by S. Benedetto et al. (1998) to find the "best" component encoders for turbo code construction are extended to find good rate-compatible puncturing patterns for a given interleaver length . This approach is shown to lead to codes that improve over previous ones, both in the maximum-likelihood sense (using transfer function bounds) and in the iterative decoding sense (through simulation results). To find simulation and analytical results, the coded bits are transmitted over an additive white Gaussian noise (AWGN) channel using an antipodal binary modulation. The two main applications of this technique are its use in hybrid incremental ARQ/FEC schemes and its use to achieve unequal error protection of an information sequence.
