Transmit antenna diversity transmission method and device using a circulating carrier unit transition

The present invention relates to a technique for applying the multiple transmit antennas in a wireless communication system. The present invention is a modulated symbol by a discrete Fourier transformation, with respect to the resource mapper, the respective frequency ranges stream to map discrete Fourier transform spread section for generating a frequency domain symbol, the frequency-domain symbols to a plurality of frequency domain streams separately determined a plurality of time domain streams: (inverse discrete Fourier transform IDFT) to the respective frequency ranges stream circulating shift (cyclic shift) circular transition portion and each of the inverse discrete Fourier transform the cyclic shifted frequency domain streams which according to the cyclic shift value produced, and provides a transmission apparatus characterized in that it comprises the use the antenna corresponding to each time-domain transmission signal streams for transmitting the time-domain stream to a receiving device section. According to the invention a single carrier frequency division multiple access multiple antennas while maintaining a low:: (Peak to Average Power Ratio PAPR) (SC-FDMA Single Carrier Frequency Division Multiple Access) mobile communication system, the maximum / average power ratio used to transfer data, and can be another orthogonal frequency division multiple access and code division multiple access scheme, such as a typical wireless communication system, even a new type of transmit diversity transmission, including. SC-FDMA, Single Frequency Division Multiple Access, MIMO, PAPR
