    • The present invention relates to an apparatus and method for variable fast Fourier transform. According to an embodiment of the present invention, two n-point fast Fourier transform (FFT) processors are used to generate two n-point FFT output data or one 2n-point FFT output data. The one 2n-point input data is alternately input to the two n-point FFT processors. Each of the two n-point FFT processors selects a twiddle factor for the n-point input data or the 2n-point input data and performs fast Fourier transform. A butterfly operation is performed on signals obtained by performing fast Fourier transform on the 2n-point input data signal, and the processed signals are aligned in an output order. According to this structure, it is possible to realize a fast Fourier transform hardware engine that selectively performs multi-frequency allocation in a base station system that supports the multi-frequency allocation.

    • The present invention relates to a URL providing apparatus and a method thereof, and a mobile station that accesses the Internet by using the provided URL, and an Internet access method thereof. The mobile station attaches an RF-ID tag that stores an RF-ID tag value corresponding to identification information of the mobile station thereto, and thus when a user brings the mobile station into an interrogation range of an RF-ID reader included in the URL providing apparatus, the URL providing apparatus receives the corresponding RF-ID tag value from the RF-ID reader. When the URL providing apparatus acquires an IP address of the mobile station by using the received RF-ID tag value and provides a URL to the mobile station by using the acquired IP address, the mobile station automatically accesses the Internet by using the URL. Such an Internet access method can minimize additional cost of the mobile station and simplify an Internet access process to a specific URL.
    • 本发明涉及一种URL提供装置及其方法,以及通过使用提供的URL访问因特网的移动台及其互联网访问方法。 移动台附加存储与移动站的识别信息相对应的RF-ID标签值的RF-ID标签,因此当用户将移动站带入包含在URL中的RF-ID读取器的询问范围 提供装置,URL提供装置从RF-ID读取器接收对应的RF-ID标签值。 当URL提供装置通过使用接收的RF-ID标签值获取移动站的IP地址并通过使用所获取的IP地址向移动站提供URL时,移动站通过使用URL自动访问因特网。 这样的因特网接入方法可以使移动站的附加成本最小化,并简化对特定URL的因特网访问过程。
