Effects of GSM-R Signals Correlation on Performance of Co-channel Interference
Gang Zhu · Computer Technology and Development · 2013
In order to better play a role,in GSM-R mobile communication network construction should pay special attention to interference problem.First derive the probability of co-channel interference in GSM-R system where the system is linear covered.And then,derive the probability of co-channel interference applying the Wilkinson method which signals undergo correlated shadowing fading where the system is nonlinear covered.In the end,through the simulation analysis,tested that the probability of co-channel interference is decreasing with increasing the co-channel reusing group,the correlation between co-channel interference undergoing correlated log-normal shadowing has little impact on the probability of co-channel interference,the correlation between useful signal and the each co-channel interference signal has great influence on the probability of co-channel interference in GSM-R system.
