MODULATION SIGNAL ANALYSIS DEVICE AND MODULATION SIGNAL ANALYSIS METHOD

摘要

PROBLEM TO BE SOLVED: To enable a wideband OFDM modulated signal to be measured and analyzed without lowering a bit resolution.;SOLUTION: A plurality of division frequency ranges for dividing the channel width of an OFDM modulated signal are set from an input setting unit 2. An input processing unit 3 takes in the OFDM modulated signal by dividing it up in time for each of the plurality of division frequency ranges, and writes, into a storage unit 4, the measurement result based on I, Q signals obtained by quadrature-demodulating the taken-in OFDM modulated signal for each of the plurality of division frequency ranges. A data processing unit 5 couples the measurement results for plurality of division frequency ranges together so as to match or include the channel width.;COPYRIGHT: (C)2014,JPO&INPIT
