Patent ID: 8520610

Claim:
A method of transmitting a signal in a transmitter, the method comprising: preparing a plurality of sub-streams; independently performing channel coding on each of the sub-streams; mapping the channel coded sub-streams to modulation symbols, wherein different channel coded sub-streams are mapped to different modulation symbols; generating symbols by applying a discrete Fourier transform (DFT) to the modulation symbols; mapping the symbols generated by the DFT to subcarriers; and transmitting signals corresponding to the symbols to a receiver, wherein the transmitter is a single carrier frequency division multiple access (SC-FDMA) transmitter, wherein the signals include a plurality of SC-FDMA symbols, and wherein one of the SC-FDMA symbols is generated by using at least part of the modulation symbols from a first sub-stream and part of the modulation symbols from a second sub-stream different from the first sub-stream among the plurality of sub-streams prepared by the transmitter.
