Abstract:
1. A method for transmitting data in a communication system, the method comprising the steps of: repeatedly processing an input signal a number of times; performing Space-Frequency Block-Coded (SFBC) coding on the repeatedly processed input signals and outputting at least two signal blocks in parallel; and inserting a cyclic prefix (CP) in the signal blocks and transmitting the CP-inserted signal blocks via associated transmission antennas using a single carrier, wherein the step of outputting at least two signal blocks in parallel comprises: demultiplexing the repeatedly processed input signals including N input samples into even transmission samples and odd transmission samples, each sample having a period of N/2; making transmission sample pairs using adjacent even transmission samples and odd transmission samples among the separated even transmission samples and odd transmission samples; inserting ‘0’s between the transmission sample pairs according to the number of repetitions; and generating the first signal block and the second signal block using the ‘0’-inserted even transmission sample pairs and odd transmission sample pairs.
