Claim:
1. A method for wireless communication at a wireless device, comprising: forming a first symbol vector comprising a first modulation symbol sequence, a second modulation symbol sequence, a first set of cyclic prefixes having a first length, and a first set of cyclic postfixes having a second length; forming a second symbol vector comprising a third modulation symbol sequence, a fourth modulation symbol sequence, a second set of cyclic prefixes having the first length, and a second set of cyclic postfixes having the second length, the third modulation symbol sequence being generated based on the second modulation symbol sequence, and the fourth modulation symbol sequence being generated based on the first modulation symbol sequence; generating a first single-carrier frequency division multiple access (SC-FDMA) symbol comprising the first symbol vector for a first transmit antenna; generating a second SC-FDMA symbol comprising the second symbol vector for a second transmit antenna; and transmitting the first SC-FDMA symbol from the first transmit antenna and the second SC-FDMA symbol from the second transmit antenna within a same SC-FDMA symbol period to achieve transmit diversity.
