Abstract (en)
[origin: EP1069707A1] A space time transmit diversity scheme using two antenna (9, 10) in which a data block of symbols (D22) is transmitted simultaneously with a complex conjugate of another block (D21*). With suitable receiver (15) processing, the symbols can be recovered with only a small complexity increase. The invention has a particular application to CDMA systems operating in TDD mode. <IMAGE>
