Title:
SIGNAL GENERATION METHOD, TRANSMISSION DEVICE, RECEPTION METHOD, AND RECEPTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2014/087674
Kind Code:
A1
Abstract:
A signal generation method used for a transmission device which transmits multiple transmit signals from multiple antennas at the same frequency band and at the same time, wherein when the power of a first transmit signal is to be changed more than that of a second transmit signal during the generation process of the first transmit signal and second transmit signal, mapping is carried out prior to the power change such that the minimum Euclidean distance between signal points which the first transmit signal can possibly have becomes longer than the minimum Euclidean distance between signal points which the second transmit signal can possibly have.
