An Optimal Model for Repeater Coordination

摘要

Because of the limitation from line-of-sight transmission and reception, there is a necessity of repeaters to pick up weak signal, amplify them and retransmit them on a different frequency. However, two nearby repeaters interfere between each other when they transmit the signals in similar frequencies.Our models find the minimum number of repeaters under certain limitations as the introduction mentioned in the paper.We have made substantive conclusions by methods used as follows.The Monte Carlo simulation has been perfectly" used in our models, and the simulation results are consistent with the result worked out from our model.Uses several techniques while modeling such as" optimization and substitute thoughts in a complicated system.We utilize simulation technique to test our model. It demonstrates that our method is robust.
