Abstract

In Korea, 2.3 GHz frequency band is allocated for a new mobile data service called the portable Internet service and assigned to 3-operators. So, it is important to investigate the effect of the adjacent channel interference caused by the other operators. In this paper, the effect of adjacent channel interference between operators is evaluated, taking into account the nonlinearity of RF components. The amplifiers are employed the polynomial based model and confirmed its spectrum spreading phenomenon due to their nonlinearity. Also the portable Internet service system are implemented in the physical layer to evaluate the interference effects of the other operators with the varying width of the guard band and relative power between operators
