Patent ID: 7680200

Claim:
A method for transmitting data in a communication system, which includes a transmission device and a reception device, in which the transmission device transmits a signal through at least two transmission antennas, and the reception device receives a signal through at least one reception antenna, the method comprising: encoding an input signal into frequency-domain blocks, and outputting at least two signal blocks in parallel to each other; and inserting a cyclic prefix (CP) into the output signal blocks, and outputting the signal blocks through each corresponding antenna by loading the signal blocks on a single carrier, wherein outputting the at least two signal blocks in parallel to each other comprises: demultiplexing N number of input signals to separate the input signals into even-numbered transmission samples and odd-numbered transmission samples, which have a period of N/2; and generating a first signal block and a second signal block by using the even-numbered and odd-numbered transmission samples.
