摘要： A 2N-point and N-point FFT/IFFT dual mode processor is provided. The processor includes a butterfly operator, the first and second MUXs, and the first and second N-point FFT processors. The butterfly operator receives 2N data and butterfly-operates on the received 2N data when receiving a control signal ‘0’ from the controller. The first and second MUXs respectively receive results from the butterfly operator to output the results in an increment of N when receiving a control signal ‘0’ from the controller, and respectively outputs different N data when receiving a control signal ‘1’ from the controller. The first and second N-point FFT processors N-point FFT operate on the results from the first and second MUXs and respectively output the same under control of the controller. Since the N-point FFT operation can be simultaneously performed two times at a receiver, the performance of the receiver can be enhanced.

摘要： Provided are an initial synchronization acquiring device and method in a parallel processed DS-CDMA UWB system and a DS-CDMA UWB system's receiver using the same. The initial synchronization acquiring device is constructed to include a correlator for correlating input signals and outputting correlation result values and an initial synchronizer for tuning initial symbol synchronization and frame synchronization by using the correlation result values received from the correlator and then storing combining mark values and a synchronization position value in a register, thereby making it possible to greatly decrease a system's complexity, compared to the existing method of separately designing respective modules for acquiring packet synchronization and symbol synchronization in the existing CDMA system. Also, the initial synchronization acquiring device and method additionally compensates a synchronization error caused by a frequency offset generated between clocks used by a transmitter and a receiver and thereby can be efficiently used in the high-speed and parallel-processed DS-CDMA UWB system.

摘要： An FIR filter of a DS-CDMA UWB modem transmitter and a control method thereof are disclosed. The FIR filter includes an LUT control device for outputting a resultant value of “0” to all adders if data values corresponding to upper three chips H2, M2 and L2 and lower three chips H, M and L are “000000”, and discriminating which group between a first group and a second group the upper/lower data values belong to if the upper/lower data values are not “000000”. The LUT control device provides upper or lower LUT values to the adders using the upper or lower LUT values as they are, or converts the upper or lower LUT values into 2's complements and provides the converted values to the adders according to the discriminated first or second group. The FIR filter has the effect of reducing the amount of memory by about 50% to 80% in comparison to the conventional FIR filter.

In the method, after introducing the glycol monoester, the linear aliphatic carboxylic acid and the Lewis acid type catalyst into a reactor, the reaction occurs to produce reaction products and water in the reactor; an excess of the linear aliphatic carboxylic acid forms an azeotrope with water during the reaction to be sent to a condenser through a distillation column; the linear aliphatic carboxylic acid and water passed through the condenser are divided into an organic layer and an aqueous layer in an oil water separator; and the organic layer is returned to the distillation column through a material cycling line and water in the aqueous layer is removed through a water removal line. By utilizing reactive distillation technique, water produced during the reaction is rapidly removed, and thus the reaction time can be significantly reduced and the yield of the glycol diester can be maximized.
