摘要： 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.

摘要： The present invention relates to a fast uplink ranging system and method in a mobile communication system. According to the present invention, a fast uplink ranging system transmits two pairs of ranging codes having the same value at locations spaced by half of FFT pointers. The fast uplink ranging system calculates a correlation value using the received two pairs of ranging codes. An order in which complex exponential twiddle factors for removing complex exponential terms corresponding to a time delay are searched is determined using the correlation value. Therefore, it is possible to reduce a time required for searching a timing error of a terminal using non-periodic symmetry of complex exponential twiddle factors corresponding to the timing error, compared with a known method of searching a complex exponential twiddle factor.

摘要： A conventional massage belt provides monotonous sense in use and simple massage effect caused from the rotational motion that draws a simple trajectory in only a forward or reverse direction when a particular body portion is massaged with vibration of the same rotational speed generated from a vibrating portion in which eccentric weights are installed at both sides of a motor and which is installed in a belt body tightly wrapped around the body portion to be massaged such as abdomen. The present invention provides a massage belt wherein when a relevant body portion is massaged with elliptic vibrations generated from vibration generators, in each of which a motor and an eccentric weight at a side of the motor are installed and which are installed in a belt body at a predetermined interval, continuous rotational motions variously changed due to the combination of vibrations generated from the vibration generators operating simultaneously at different rotational speeds and/or intensity of the elliptic vibrations are applied to the relevant body portion, thereby maximizing a variety of massage effects and interest occurring in use.
