Abstract  Abstract

multiple secondary antenna (801) A receiving device with multi-path reception on the same frequency band modulated signal estimation of each received signal received electric field intensity field intensity deducing part (849) deducing transmission line change of every channel of each received signal of transmission line change deducing part (806 808); the phase difference of the transmission line change deducing signal specified channel of each antenna and taking it as the phase difference of the phase difference signal output parts (851 853) and selects and outputs a signal from each received signal branch of each channel for receiving the quadrature baseband signal and the transmission line of each channel change deducing signal of signal selection part (855). Therefore the modulated signal received by a plurality of multiplexed paths demodulation which can improve the data transmission speed.

A reception apparatus includes a plurality of antennas (801) for receiving modulation signals of channels in the same frequency band an electric field intensity estimation unit (849) for estimating the reception electric field intensity of each reception signal transmission path fluctuation estimation units (806 808) for estimating a transmission path fluctuation of each channel of the reception signal phase difference estimation units (851 853) for calculating a phase difference of the transmission path fluctuation estimation signal of a predetermined channel of each antenna and outputting it as a phase difference signal and a signal selection unit (855) for selecting and outputting a reception orthogonal base band signal for isolating a signal of each channel from the reception signals and a transmission path fluctuation estimation signal of each channel. Thus by isolating and demodulating a plurality of multiplexed modulated signals received it is possible to improve the data transmission rate.
