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