Abstract:
1. A method for transmitting signals in a communication system having multiple independent transmission paths, the method comprising: a first transmission process including transmitting multiple transmission signals by mapping the multiple transmission signals to the multiple independent transmission paths according to a specific mapping rule; and a second transmission process including retransmitting the multiple transmission signals by mapping each of the multiple transmission signals to a different independent transmission path from an independent transmission path that was mapped to the transmission signal in the first transmission process, wherein the transmission signals are complex signals, and real and ideal components of the complex signals are transmitted by mapping each of the real and ideal components to different independent transmission paths in the first and second transmission processes, wherein a real component of a first complex signal among the complex signals in the first transmission process is mapped to an ideal axis of a first independent transmission path in the second transmission process, and wherein an ideal component of a second complex signal among the complex signals in the first transmission process is mapped to a real axis of a second independent transmission path in the second transmission process.
