PROBLEM TO BE SOLVED: To achieve precise diversity composition by improving an error in a calculated OFDM diversity composition ratio caused by noise included into a pilot carrier in environment having deteriorated C/N and the deterioration of the C/N after composition. SOLUTION: In a device for diversity-receiving an OFDM signal using a discrete pilot, a reception signal is subjected to Fourier transform to average the pilot carrier extracted from a frequency axis signal in a time direction, and the composition ratio in the diversity composition is calculated from the transmission path estimation result of a frequency axis based on the pilot carrier after noise is reduced.
