Co-Channel Interference Analysis of Point to Point mm-Wave Radio Links

Abstract- Point to point mm-wave radio links are being increasingly deployed because of the expansion of commercial wireless services. Providers of wireless services continue to demand systems with higher data rate and higher carrier frequency. In order to fulfill the demand unlicensed mm-wave bands have been investigated for fixed point-to-point outdoor radio applications. An analytical method is developed in this paper to study co-channel inteference of mm-wave devices in a given area. An optimum number of mmwave devices in a certain area may be drawn from the analysis. MatLab programs are also produced to simulate the approach. The simulation results are plotted to give a clear view. It is expected that the interference analysis would help to implement the mm-wave point to point communication systems in outdoor environment.
