In order to avoid local optimum site selection for the Single Frequency Network（SFN） of terrestrial digital television

this paper applies the simulated annealing algorithm in the selection process and proposes a simulated annealing-based site selection algorithm for the SFN.By combining this algorithm with the topographic factors

it optimizes the configuration probability in receiving poor site selections so that it is possible to decide whether or not it can accelerate the operation according to terrain conditions.Furthermore

it conducts a secondary development on the basis of the professional software NG

R

adioPlan.Simulation results show that this algorithm can effectively carry out site selection.
