摘要： A base station includes a center frequency setting unit, a local oscillator, a baseband processor, and an RF processor. In the event of a frequency band change, the center frequency setting unit sets a center frequency of a use frequency channel to have a predetermined offset value with respect to a center frequency before the frequency band change. The local oscillator generates an LO frequency signal according to the center frequency set by the center frequency setting unit. The baseband processor generates a downlink baseband signal. The RF processor uses the LO frequency signal to convert the downlink baseband signal into an RF signal prior to transmission.

摘要： An apparatus and method for selecting at least two users to be serviced in SDMA in an SDMA wireless communication system are provided. All users are ordered according to a predetermined rule and all possible user combinations each having at least two users are created from the ordered users. An investigation limit number is set using the capacity of a jth user combination. Or a total investigation number is reduced by comparing the interference-reflected SNR decrements of users with an investigation threshold. Therefore, the computation volume for selecting SDMA users is decreased.
