“…Such performance was almost equal to the case where there is no channel estimation at all since the statistics of the non-WSSUS process change as the data transmission proceeds, and the non-stationarities directly impact the weighted average that was carried out in the frequency domain [57,58]. In this particular case, the channel effect on the system performance due to the acceleration of the MSs was minimal and masked by its inherent non-stationarities [59]. In addition to the results presented in Figure 8, Table 5 shows the Eb/No levels that attained 10% and 1% BER for the low mobility (20 km/h and 40 km/h) and high mobility (80 km/h and 100 km/h) conditions in the three propagation scenarios described above.…”

This paper presents a simulator of non-wide sense stationary uncorrelated scattering (non-WSSUS) multipath fading channels for the performance analysis of vehicle-to-everything (V2X) communication systems. The proposed simulator is constructed with the combination of the Monte Carlo and sum-of-cisoids (SOC) principles, and it is suitable for multicarrier transmission schemes such as those defined for dedicated short-range communications (DSRC) and cellular-based V2X (C-V2X) communications. The channel simulator provides an accurate and flexible solution to reproduce the time and frequency (TF) correlation properties of non-WSSUS vehicular channels under arbitrary isotropic and non-isotropic scattering conditions. Furthermore, the proposed simulator allows velocity variations and non-linear trajectories of the mobile stations (MSs). To demonstrate the practical value of the presented simulator, we evaluate the bit error rate (BER) performance of two channel estimation techniques that are considered for IEEE 802.11p transceivers, namely the least squares (LS) estimator and the spectral temporal averaging (STA) technique. The BER performance of both channel estimators was analyzed by considering three propagating scenarios for road safety applications. Our results show that the non-stationary characteristics of the vehicular multipath fading channel have nearly no effects on the LS estimator’s BER performance. In contrast, the performance of the STA estimator is significantly affected by the channel’s non-stationary characteristics. A variation of the original STA technique that applies only a temporal averaging is introduced in this work to improve the system’s BER in non-WSSUS channels.

“…It is applied to all experiments in the same way to reach a fair evaluation. The models are sufficiently detailed to reflect the main WLAN protocol properties, and the physical channel is approximated by typical channel models found in literature [33], [34]. Future field tests are planned to include real world conditions.…”

“…The faulty transmission of a frame can be categorized into two classes: Arbitration conflicts, i.e. collisions represented by a frame error rate (FER), and effects due to properties of the wireless channel in general, which are typically represented in a vehicular environment by a Bit Error Rate (BER) [33], [34]. With respect to the CSMA/CA arbitration principles of IEEE 802.11p, the amount of collisions is related to the utilization of the channel, i.e.…”

We present a middleware-based protocol that reliably synchronizes large samples consisting of multiple frames efficiently and within application level QoS requirements over a lossy wireless channel. The protocol uses a custom retransmission scheme, exploiting the latency requirements on sample level for frame level scheduling. It can be integrated into the popular DDS middleware. We investigate some technical limits of such a protocol and compare it to existing error protocols in the software stack and in the wireless protocol and combinations thereof. The comparison is based on an Omnet++ simulation using an established wireless channel error model. For evaluation, we take a use case from automated valet parking where infrastructure data provided via a wireless link augments in-vehicle sensor data. The use case respects the related safety requirements. Results show that the application awareness of the presented protocol, significantly improves service availability by transmitting data efficiently in time even under higher frame error rates.
