    • A plurality of data signals are received over an antenna array having a plurality of antenna elements. The data signals are transmitted over a shared spectrum in a wireless communication system. A signal having each of the data signals is received over each antenna element. The plurality of data signals are grouped into a plurality of groups. The received signals of the antenna elements are matched filtered for a first group of the plurality of groups, producing a matched filtered result. Data is jointly detected of the first group using the matched filtered result. An interference correction signal is constructed using the detected data for each antenna element. The interference cancelled result is subtracted from the received signal of each antenna element, producing an interference cancelled result for each antenna element. Data is successively detected for remaining groups using the interference cancelled result for each antenna element.
    • 通过具有多个天线元件的天线阵列接收多个数据信号。 数据信号通过无线通信系统中的共享频谱传输。 在每个天线元件上接收具有每个数据信号的信号。 多个数据信号被分组成多个组。 天线元件的接收信号对于多个组中的第一组进行匹配滤波,产生匹配的滤波结果。 使用匹配的过滤结果联合检测第一组的数据。 使用每个天线元件的检测数据构建干扰校正信号。 从每个天线元件的接收信号中减去干扰消除结果,产生每个天线元件的干扰消除结果。 使用每个天线元件的干扰消除结果对剩余组连续检测数据。
