    摘要: A method and apparatus for transmitting data having time diversity and data having time-frequency diversity, and a pattern generating method for the same are disclosed. The apparatus enables Tx data to have time diversity or time frequency diversity using a predetermined pattern multiplied by Tx data of a time domain or Tx data of time and frequency domains. The apparatus makes a cyclic delay diversity (CDD) scheme to have the diversity of time and frequency domains, and may acquire an additional diversity gain by a combination of the above-mentioned methods.

    摘要: A method of transmitting data in a wireless communication system is provided. The method includes generating duplicate data by using repetition coding, the duplicate data being the same as original data, shifting the phase of the duplicate data, and transmitting the original data and the phase-shifted duplicate data. The duplicate data is mapped to a modulation symbol having a different size or phase as that of the original data, thus to reduce the PAPR unlike the general repetition coding.
