METHOD AND APPARATUS FOR LAYER SHIFTING IN MIMO COMMUNICATION SYSTEM

摘要

PURPOSE: A method and an apparatus for layer shifting in a MIMO communication system are provided to use a multi-antenna technique with an orthogonal frequency division multiple access technique while maintaining the characteristics of a single carrier frequency division multiple access signal having a low maximum/minimum power ratio. CONSTITUTION: A method for layer shifting in a MIMO communication system comprises the steps of: dividing at least one codeword comprising modulation symbols(810); mapping at least one divided codeword to plural layers; mixing the plural layers by DFT symbol unit(820); performing a DFT conversion for the mixed plural layers(830); and mapping the plural layer to at least one antenna port(840-850).
