    • The present invention relates to a transmitting device and a receiving device in a wireless orthogonal frequency division multiplex (OFDM) communication system with space time transmit diversity (STTD). Further, the present invention relates to a channel estimation method for performing a channel estimation in such a wireless communication system, in which the transmitting device comprises a first and a second antenna for transmitting signals with space time transmit diversity. The first and the second antenna means are arranged spaced apart from each other in a space diversity arrangement, whereby first and second pilot symbols are transmitted via said first and said second antenna means, respectively. Some of the second pilot symbols are orthogonal to corresponding ones of the first pilot symbols, so that a channel estimation to separately determine the transmission quality of signals transmitted from the first and the second antenna means, respectively, can be performed in a receiving device which receives the signals with only one single antenna.
    • 本发明涉及具有空时发射分集(STTD)的无线正交频分复用(OFDM)通信系统中的发射设备和接收设备。 此外,本发明涉及一种用于在这种无线通信系统中执行信道估计的信道估计方法,其中发射设备包括用于发射具有空时发射分集的信号的第一和第二天线。 第一和第二天线装置以空间分集配置彼此间隔开布置,由此第一和第二导频符号分别通过所述第一和第二天线装置发射。 一些第二导频符号与相应的第一导频符号正交,从而可以分别在接收装置中执行分别确定从第一和第二天线装置发送的信号的传输质量的信道估计,该接收装置 只有一个天线接收信号。
