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： The present invention relates to a current cell driving circuit in a digital-to-analog converter. The current cell driving circuit limits the potential of differential control signals to a given potential level by means of a voltage limiter using a parasitic capacitance of a transistor. Therefore, the present invention can effectively limit the potential of differential control signals DP and DN without compromising the power consumption and the circuit area and also can minimize the transfer time.

摘要： A high speed ROM-based Nyquist FIR filter which is capable of enhancing a modulation speed without increasing the operational frequency of the filter by overcoming the problems encountered in the conventional digital modulation ROM-based FIR filter. Therefore, it is possible to increase the modulation speed by the interpolation ratio without increasing the operational frequency of the filter compared to the method of using a conventional FIR filter using one ROM. Accordingly, the high speed ROM-based Nyquist FIR filter according to the present invention is well adaptive to the modulation FIR filter of a broadband digital communication which requires a high speed data processing capability.
