    • An antenna array for the transmission of signals is disclosed which comprises a plurality of antenna elements connected to a plurality of transceivers. The plurality of transceivers receive transceiver signals for transmission to the plurality of antenna elements. The antenna comprises a failure detector or monitoring and control system connected to the plurality of transceivers, which autonomously detects malfunction of the individual transceivers and reports this to the signal processor without involvement of the transmitter and receiver. The antenna array also comprises a signal processor connected to the plurality of transceivers and adapted to weight using complex values the transceiver signals for automatically compensating for power losses by tilt adjustments and for interference by suppression of sidelobes of the signals based on the information from the failure detector or monitoring and control system.
    • 公开了一种用于信号传输的天线阵列,其包括连接到多个收发器的多个天线元件。 多个收发器接收收发信号以传输到多个天线元件。 天线包括连接到多个收发器的故障检测器或监视和控制系统,其自主地检测各个收发器的故障,并将其报告给信号处理器而不涉及发射器和接收器。 天线阵列还包括连接到多个收发器的信号处理器,并且适于使用复数值来加权收发器信号,用于通过倾斜调整自动补偿功率损耗,并通过基于来自故障的信息抑制信号的旁瓣来进行干扰 检测器或监控系统。

    • Data symbols, transmitted by OFDM radio using at least two transmission antennae, are coded by a DSTBC coding and a DSTFBC coding. Two adjacent data symbols of a selected sub-carrier are provided for initializing a DSTFBC coding in a sub-carrier direction and are used for DSTFBC coding of similarly positioned data symbols in further sub-carriers in the sub-carrier. The DSTFBC coding is carried out from the data symbols of the first sub-carrier direction. In each sub-carrier the two data symbols formed by DSTFBC coding are used for initializing a DSTBC coding in the OFDM symbol direction. In the reverse direction, two sequential DSTBC coded data symbols on a first sub-carrier for initializing a DSTFBC coding in a sub-carrier direction and are used for DSTFBC coding of similarly positioned data symbols in further sub-carriers for DSTFBC coding from the data symbols of the first sub-carrier over the adjacent sub-carriers.
    • 使用至少两个发送天线的OFDM无线电发送的数据符号通过DSTBC编码和DSTFBC编码进行编码。 提供选择的子载波的两个相邻数据符号用于在子载波方向初始化DSTFBC编码,并且用于子载波中另外的子载波中类似定位的数据符号的DSTFBC编码。 从第一子载波方向的数据符号执行DSTFBC编码。 在每个子载波中,由DSTFBC编码形成的两个数据符号用于在OFDM符号方向初始化DSTBC编码。 在相反方向上,在第一子载波上用于初始化副载波方向上的DSTFBC编码的两个连续的DSTBC编码数据符号,并用于从数据中进行DSTFBC编码的另外的子载波中的类似位置的数据符号的DSTFBC编码 相邻子载波上的第一子载波的符号。
