摘要： PROBLEM TO BE SOLVED: To obtain a communication device capable of obtaining excellent characteristics by correcting device distortion and propagation distortion.
SOLUTION: The communication device for reception includes: a high frequency demodulation circuit 2 for converting a received signal into a baseband signal; an analog/digital conversion circuit 3 for converting the baseband signal converted by the high frequency demodulation circuit into a digital signal; and a baseband demodulation circuit 5 which demodulates the baseband signal from the digital signal converted by the analog/digital conversion circuit and outputs the demodulated baseband signal, wherein, between the analog/digital conversion circuit 3 and the baseband demodulation circuit 5, a frequency equalization circuit 4 for reception is provided which corrects device distortion and propagation distortion.
