“…In the case of Rician fading, however, according to (20) and (21), y m,n and h m,n are not zero-mean because of the LOS component, and then the CDF of complex ratio distribution derived in [9] and [27] can no longer be applied. Thus, we introduce another method to calculate F Re,x m, n (λ, x) in the following.…”

“…The Rician channel is another important and more general channel model by the truth that there is likely to be a direct path component, i.e., the line of sight (LOS) path, in many practical environments. This phenomenon is strengthened with the trend toward higher frequency band usage [19] and in some specific communication scenarios expected in the future, such as D2D communications, where the beam width of the antenna and the distance between the transceivers may both be much limited [20], [21]. Therefore, in this study we aim to develop a general analytical framework for BEP evaluation that covers both Rayleigh and Rician fading, flat and doubly-selective channels, and FBMC-OQAM and OFDM systems.…”

Filter bank multicarrier with offset quadrature amplitude modulation (FBMC-OQAM) is considered an alternative to conventional orthogonal frequency division multiplexing (OFDM) to meet the various requirements proposed by future communication networks. Among the different perspectives on the merits of FBMC-OQAM and OFDM, a straightforward metric is the bit error probability (BEP). This paper presents a general analytical framework for BEP evaluation that is applicable to FBMC-OQAM and OFDM systems in both Rayleigh and Rician multipath fading channels. Explicit BEP expressions are derived for Gray-coded pulse amplitude modulation (PAM) and square quadrature amplitude modulation (QAM) signals with arbitrary constellation sizes. The theoretical analysis results show excellent agreement with the numerical simulation results in different channel scenarios.

“…Accurate channel models are always important for the design of wireless communication technologies and the evaluation of their performance. However, existing stochastic models such as theoretical geometry-based models [5]- [7], the 3GPP spatial channel model (SCM) [8], the WINNER II SCM enhanced (SCME) [9], and the models proposed in the series of European cooperative for scientific and technical research (COST) activities [10] focus more on micro and macro cellular scenarios, without considering the HST channels thoroughly. Recently, some models [11]- [14] have been proposed for vehicular communication channels observed in fast timevariant scenarios.…”

In this paper, a recently conducted measurement campaign for high-speed-train (HST) channels is introduced, where the downlink signals of an in-service Universal Mobile Terrestrial System (UMTS) deployed along an HST railway between Beijing and Shanghai were acquired. The channel impulse responses (CIRs) are extracted from the data received in the common pilot channels (CPICHs). Within 1318 km, 144 base stations (BSs) were detected. Multipath components (MPCs) estimated from the CIRs are clustered and associated across the time slots. The results show that, limited by the sounding bandwidth of 3.84 MHz, most of the channels contain a single line-of-sight (LoS) cluster, and the rest consists of several LoS clusters due to distributed antennas, leaking cable, or neighboring BSs sharing the same CPICH. A new geometry-based random-cluster model is established for the clusters' behavior in delay and Doppler domains. Different from conventional models, the time-evolving behaviors of clusters are characterized by random geometrical parameters, i.e., the relative position of BS to railway, and the train speed. The distributions of these parameters, and the per-cluster path loss, shadowing, delay, and Doppler spreads, are extracted from the measurement data. Index Terms-Geometry-based stochastic model, high speed train, random cluster model, time-variant channel, Universal Mobile Terrestrial System.

“…With respect to the coexistence of V2I and V2V links in vehicular networks, this scenario can easily be compared with D2D underlaying cellular networks, in which the D2D communication mode can be used to support V2V communications in order to increase the spectrum efficiency. However, because of the existence of unique vehicular scenarios [20][21][22] with highspeed vehicle mobility and fast time-variant channels, the traditional D2D mode cannot be adopted directly for V2V communications. Thus, significant modifications and improvements are needed.…”

Vehicular network communication technology is currently attracting a considerable amount of attention. We consider a scenario in which vehicular communication nodes share the same spectrum resources and generate interference with other nodes. Compared with traditional interference-avoiding vehicular communications, this paper aims to increase the number of accessed communication links under the premise of satisfying the required QoS. In our research, communication nodes have opportunities to select relay nodes to both help improve their data transmissions and reduce their transmit power in order to decrease interference with other links while still satisfying their QoS requirements. Based on these objectives, we propose an innovative interference management method that considers link selection, power adaption, and communication mode selection simultaneously to maximize the number of communication links with the lowest power cost. Compared with traditional link-selection and power-adaption interference management schemes, the proposed scheme improves QoS satisfaction with high energy efficiency. Simulation results demonstrate both the efficiency and the effectiveness of the proposed scheme.Keywords: vehicular networks, interference management, link selection, power adaption, energy efficiencyT.
