“…The PDF p (z) of SLDS processes (t) presented in (13) can be verified from the literature (see, e.g., [11]). The condition ρ = 0 indicates the absence of the LOS component in the direct link from the source mobile station to the destination mobile station.…”

“…The novelty in our approach is that, we model the envelope of the amplify-and-forward relay channel as a single-LOS double-scattering (SLDS) fading channel, i.e., the superposition of a deterministic LOS component and a zero-mean complex double Gaussian process. The PDF of the envelope of SLDS fading channels has been derived in [11]. However, other important statistical quantities like the PDF of the phase, LCR, and ADF have not been studied so far.…”

Recently, mobile-to-mobile (M2M) cooperative network technology has gained considerable attention for its promise of enhanced system performance with increased mobility support. As this is a new research field, little is known about the statistical properties of M2M fading channels in cooperative networks. So far, M2M fading channels have mainly been modeled under the assumption of non-line-of-sight (NLOS) conditions. In this paper, we propose a new model for M2M fading channels in amplify-and-forward relay links, where it is assumed that a line-of-sight (LOS) component exists in the direct link between the source mobile station and the destination mobile station. Analytical expressions will be derived for the main statistical quantities of the channel envelope, such as the mean value, variance, probability density function (PDF), level-crossing rate (LCR), and average duration of fades (ADF) as well as the channel phase. Our results show that the statistical properties of the proposed M2M channel are quite different from those of double Rayleigh and double Rice channels. In addition, a high-performance channel simulator will be presented for the new M2M channel model. The developed channel simulator is used to confirm the correctness of all obtained theoretical results by simulations.

“…This statistical model has been developed for urban cellular radio systems, however is not very realistic for mobile-to-mobile links such as in intervehicular communications. Through experimental and theoretical investigations, cascaded Rayleigh fading has been proposed [5], [6] for a more precise characterization of mobile-to-mobile channel. In this paper, we investigate the error rate performance of a relayassisted AF cooperative system over cascaded Rayleigh fading channels.…”

Abstract-In this letter, we consider the deployment of distributed space-time trellis codes (STTCs) for user cooperation. We derive a pairwise error probability (PEP) expression for distributed STTCs over cascaded Rayleigh fading channels. Using the derived PEP expression, we determine a code design criterion and propose novel 4-/8-/16-state 4-PSK and 8-/16-state 8-PSK distributed STTCs through a systematic code search. We confirm the superiority of the proposed codes through extensive MonteCarlo simulations.Index Terms-Error rate performance, distributed space-time coding, amplify-and-forward relaying, cascaded Rayleigh fading channels.

“…The resulting channel, obtained by combining the SMS-MR-DMS link and the SMS-DMS link is named as the NLSS channel model. The signal received after traversing through NLSS channels is composed of a sum of a single and a double scattered component [20,21]. Studies conducted for NLSS channels provide us with a thorough analysis of the PDF and CDF of NLSS channels.…”

“…However, there is a lack of information regarding the LCR and ADF of NLSS channels in the literature. The extension of NLSS fading channel models, when a significant LOS component is present between the direct SMS-DMS link, results in SLSS channels [20,21]. SLSS channels have only been partially analyzed so far just as NLSS channels.…”

This paper deals with the modeling and analysis of narrowband mobile-to-mobile (M2M) fading channels for amplify-and-forward relay links under line-of-sight (LOS) conditions. It is assumed that a LOS component exists in the direct link between the source mobile station (SMS) and the destination mobile station (DMS), as well as in the links via the mobile relay (MR). The proposed channel model is referred to as the multiple-LOS second-order scattering (MLSS) channel model. The MLSS channel model is derived from a second-order scattering process, where the received signal is modeled in the complex baseband as the sum of a single and a double scattered component. Analytical expressions are derived for the mean value, variance, probability density function (PDF), cumulative distribution function (CDF), level-crossing rate (LCR), and average duration of fades (ADF) of the received envelope of MLSS channels. The PDF of the channel phase is also investigated. It is observed that the LOS components and the relay gain have a significant influence on the statistics of MLSS channels. It is also shown that MLSS channels include various other channel models as special cases, e.g., double Rayleigh channels, double Rice channels, single-LOS doublescattering (SLDS) channels, non-line-of-sight (NLOS) second-order scattering (NLSS) channels, and single-LOS second-order scattering (SLSS) channels. The correctness of all analytical results is confirmed by simulations using a high performance channel simulator. Our novel MLSS channel model is of significant importance for the system level performance evaluation of M2M communication systems in different M2M propagation scenarios. Furthermore, our studies pertaining to the fading behavior of MLSS channels are useful for the design and development of relay-based cooperative wireless networks.
