METHOD AND APPARATUS FOR TRANSMITTING DATA BASED ON FREQUENCY HOPPING

摘要

A method and a device for transmitting data based on frequency hopping are provided. A method for transmitting a multi-stream CPDMA-based signal comprises: a step that a terminal allocates a plurality of data symbols to a plurality of data streams, respectively, based on a frequency hopping pattern; a step that a terminal applies a DFT function and an M times repetition function for the allocated data symbol to the each of the data streams; a step that the terminal applies a spectral weighting vector to the each of the data streams to which the DFT function and M-times repetition function are applied; a step that the terminal generates the multi-stream CPDMA-based signal by performing an IDFT function and a cyclic prefix addition for the data streams to which the spectral weighting vector is applied. The spectral weighting vector can be a vector to determine a frequency band which is used by the each of the data streams.
