SIGNAL GENERATION METHOD, TRANSMITTING DEVICE, RECEIVING METHOD AND RECEIVING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a signal generation method, a transmitting device, a receiving method and a receiving device of MIMO (Multiple-Input Multiple-Output), which can improve reception quality in a LOS (Line of Sight) environment.SOLUTION: A transmitting device comprises: a mapping part 15004 which performs data modulation on two streams when transmitting two streams, depending on a modulation method and a bit number; power change parts 15006A and 15006B perform power change of each data signal modulated based on a control signal 15012; a weighted synthesis part 15008 sets a predetermined precoding matrix based on the control signal 15012; power change parts 15010A and 15010B perform power change on each signal after weighted synthesis, based on the control signal 15012.SELECTED DRAWING: Figure 150
