| Abstract(in English) | Design of approximate Nyquist filters consisting of Butterworth and FIR filters is studied. Signal to intersymbol interference ratio PISI and signal to interchannel interference ratio PICI are calculated in order to evaluate performances of the designed filters in QPSK transmission systems. The tap number of FIR filters is from 16 to 128. The order of Butterworth filters is 0.4, 0.7 and 1.0 times clock rate. The roll-off factor is from 0.1 to 1.0. The results are summarized in a table showing minimum structure of filters (corresponding to the minimum number of taps in FIR) for the roll-off factor from 0.1 to 1.0 (0.1 step), PISI of more than 30bD and PICI equal 60dB, under the condition that the same frequency is obtained as in a QPSK system using ideal Nyquist filters. |
