摘要： Disclosed is an apparatus for performing both FHT (Fast Hadamard Transform) and FFT (Fast Fourier Transform). This apparatus determines the phase coefficients as constantly “1” when performing the FHT, and changes the input order of input data to a reverse order of bits when performing the FFT. In addition, the apparatus, which can process a plurality of input data sets simultaneously, classifies the received signals into multi-path signals and multi-antenna signals, thus processing the multi-path signals separately from the multi-antenna signals, or directly processes multi-antenna signals.

摘要： A region searcher, a method of driving the same, and a code searcher using the same are disclosed. When a predetermined region is iteratively searched, the energy value corresponding to the same hypothesis location value is stored by using a searcher having divided two buffers, thereby the implementation complexity thereof can be remarkably reduced, without using a simple memory.In addition, in case where the region is iteratively searched in the state of the deteriorated signal-to-noise ratio to find the energy value at one hypothesis location and in case where the region must be iteratively searched because of the restriction which the size of the matched filter can be not increased, the implementation complexity thereof can be remarkably reduced.

摘要： A symbol combining method in a Rake receiver, which relates to a method for combining the demodulated multi-path signals in a demodulation process of a code division multiple access communication system. The symbol combining method, a Rake receiver using the symbol combining method and a method for driving the Rake receiver, remarkably reduce a hardware complexity of a FIFO register used to regulate a timing synchronization of each finger in Rake receiver by using a new algorithm in a combining process when a CDMA communication system combines a plurality of multi-path signals therebetween. Whereas a conventional combining algorithm uses an individual FIFO register every finger so as to adjust a timing synchronization of each symbol before combining a demodulated symbol, the inventive combining algorithm performs a symbol combining operation as well as a timing synchronization of a symbol at the same time, and performs a combining action by using only one FIFO register irrespective of the number of fingers.

摘要： A method for stable channel estimation to increase frequency band efficiency that is lost by using a pilot, and to reduce the complexity and the sensitivity to channel zero. The method includes generating an i-th symbol block Si including N carriers, performing an inverse fast Fourier transform (IFFT) operation on the i-th symbol block, and forming an orthogonal frequency division multiplexing (OFDM) symbol block. The method also includes attaching a guard interval sample in front of the i-th OFDM symbol block Ui and forming at least one OFDM symbol block Ui,cp. The method further includes modeling the formed OFDM symbol block Ui,cp with a channel finite impulse response (FIR) filter and estimating channel impulse response using signals yi received through a channel.

摘要： A multipath searching device includes a radio front-end for converting a received radio signal into a baseband signal and for outputting the baseband signal. A profile calculating unit is included for calculating and outputting the multipath profile of the baseband signal. A first detector determines whether or not the radio signal traveled along a multipath is having a short-delay path by comparing the peak value of the multipath profile with a profile value of a predetermined position time interval before or after the peak of the multipath profile. A path selector receives the multipath profile and the detection result of the first detector, generates time delay information for each path, and separates many paths along which the radio signal traveled. A receiving unit receives the time delay information of the paths, despreads the baseband signal, and combines despread signals.
