Linear Diversity Combining Techniques Employed in Car-to-X Communication Systems

MRC performance benefit in V2V communication systems in urban traffic scenarios

“…On the one hand, we are interested in comparing the MRC performance using a more realistic channel model that includes subchannel correlation instead of ideally uncorrelated channels as assumed in [7]. On the other hand, we intend to analyze a possible extension of the maximum communication range when multiple receive antennas are used.…”

“…However, in [9] it is shown that advanced estimation methods and further improvement lead to a quite good system performance compared to an ideal channel estimator. Finally, the MRC technique described in [5,7] is used to combine all incoming receive signals.…”

“…Since real-world measurements require a lot of effort, we are interested in a simulation-based analysis of achievable diversity gains in vehicular environments. In [7], different diversity combining techniques have been applied to vehicular communication systems and evaluated with respect to the achieved performance benefit. The authors have assumed completely uncorrelated subchannels in this work.…”

“…Using a deterministic channel model, the subchannel correlation is included in this work leading to more realistic results compared to those presented in [7]. The analysis also takes different antenna configurations with two, three or four receive antennas into account.…”

Wireless Multicasting with Diversity Combining Techniques

“…al evaluated results of different linear diversity combining techniques. They showed that the use of multiple receive antennas in combination with adequate signal combining can improve the reliability of communication system even under poor SNR [4] . A. Arokiamarie Johnsi, V. Saminadan proposed diversity combining techniques in Free space Optical (FSO) communication system to mitigate the harmful effect of atmospheric turbulence [5] .…”
