METHOD AND APPARATUS FOR TRANSMITTING DATA WITH TIME DIVERSITY AND/OR TIME-FREQUENCY DIVERSITY, AND PATTERN-GENERATING METHOD TO BE USED IN THE SAME

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.
