    • In an iterative receiver, a signal detector estimates interference from an estimated transmitted signal, and cancels the estimated interference from a signal received through an antenna. A decoder performs channel decoding by using the interference cancelled received signal. A soft decision unit performs a soft decision process on the transmitted signal by using the channel decoded signal. A channel estimator estimates a channel by using the soft decision applied transmitted signal and the received signal. A covariance estimator estimates covariance on the sum signal of the interference and noise by using the soft decision applied transmitted signal, the received signal, and the estimated channel. A hard decision unit determines the transmitted signal by using the channel decoded signal after interference cancellation, channel decoding, estimated transmitted signal updating, channel estimation, and covariance estimation are iterated a number of times.
    • 在迭代接收机中,信号检测器估计来自估计的发射信号的干扰,并且从通过天线接收的信号中消除所估计的干扰。 解码器通过使用干扰消除的接收信号来执行信道解码。 软判决单元通过使用信道解码信号对所发送的信号进行软判定处理。 信道估计器通过使用软判决应用发送信号和接收信号来估计信道。 协方差估计器通过使用软判决应用发射信号,接收信号和估计信道来估计干扰和噪声的和信号的协方差。 硬判决单元通过使用干扰消除之后的信道解码信号来确定发送信号,信道解码,估计的发送信号更新,信道估计和协方差估计被多次重复。
