“…7, was chosen due to its popularity with researchers in traffic pattern simulation [10]. The velocities of the vehicles were obtained from SUMO and used to generate an appropriate Rayleigh fading through the GUI PHY simulator [9]. Table 1, data rates that involved puncturing performed poorly in comparison to data rates that didn't utilize puncturing; poorly being a higher .…”

“…Here the solid line rectangle surrounds the region of communication range, the dashed rectangle shows the Hidden nodes from the desired user, and the dotted lined rectangle represents the regions where interfering nodes can cause secondary interference to users within the communication range. Defining the minimum SNR values required for the different data rates has been accomplished using our OFDM physical simulator [9]. The simulation parameters have been set to calculate the minimum SNR to provide communication with a maximum of 20% packet error.…”

The DSRC safety messaging system was initially proposed for emergencies and vehicle safety applications; having a high reliability is a major design factor. Due to the fact that the DSRC system has different data rates according to its modulation and coding schemes, a minimum SNR threshold for different data rates is required for successful message transmission. This paper provides the different SNR ratios for the varying data rates used in the current DSRC IEEE802.11p standard. More specifically, our model and simulations focus directly on how the SNR for various data rates using repetition based protocols decreases with distance and with added interfering terminals. We have also explored the effects of changing packet length and are shown to have negligible effects for the minimum SNR levels. Additionally, we propose an interference model that uses the distance between vehicles and the transmission power based on the minimum SNR values obtained in this paper and simulated the probability of successful transmission for different data rates. This allows us to solve for the optimal data rate for use in DSRC safety messaging systems. The simulation traffic model used is the well known SUMO traffic model, and we simulated for both highway and urban traffic scenarios while taking hidden terminals into account.Index Terms-DSRC, ITS, IEEE802.11p, Signal-to-noise ratio, Interference range, Communication range, Multi user interference

Orthogonal Frequency Division Multiplexing (OFDM) is a particular case of multicarrier transmission in which, higher data rates are achieved using carriers that are densely packed. In this paper, implementation of OFDM communication system with channel estimation and synchronization is carried out and the bit error rate (BER) of OFDM system with and without channel estimation is observed and correspondingly a plot is traced. The choice has been made because of the advantages that OFDM and SDR has shown in terms of channel capacity and cost. Implementation of the prototype has been in GNU Radio; an open source software.

“…Therefore, different promising multi-antenna and multicarrier communication schemes are considered as key techniques that can fulfil high spectral efficiency demand of fourth generation (4G) cellular wireless systems and potentially leading to gigabits communications. The most important schemes are multiple-input multiple-output (MIMO) [1][2][3], orthogonal frequency division multiplexing (OFDM) [4], multicarrier code-division multiple-access (MC-CDMA) [5], the hybrid combinations MIMO-OFDM [6], MIMO-CDMA [7,8], and MIMO-MC-CDMA [9]. However, it is well known that propagation channel modelling have a crucial impact on the performance evaluation of any wireless communication system such as reliability and capacity.…”

In this paper, a generalized method is proposed for the accurate simulation of equal/ unequal power correlated Rayleigh fading channels to overcome the shortcomings of existing methods. Spatial and spectral correlations are also considered in this technique for different transmission conditions. It employs successive coloring for the inphase and quadrature components of successive signals using real correlation vector of successive signal envelopes rather than complex covariance matrix of the Gaussian signals which is utilized in conventional methods. Any number of fading signals with any desired correlations of successive envelope pairs in the interval [0, 1] can be generated with high accuracy. Moreover, factorization of the desired covariance matrix is avoided to overcome the shortcomings and high computational complexity of conventional methods. Extensive simulations of different representative scenarios demonstrate the effectiveness of the proposed technique. The simplicity and accuracy of this method will help the researchers to study and simulate the impact of fading correlation on the performance evaluation of various multi-antenna and multicarrier communication systems. Moreover, it enables the engineers for efficient design and deployment of new schemes for feasible wireless applications. Generation of correlated
