    • A multipath interference cancellation method in a multicode code division multiple access (cdma) system comprising a transmitter and a receiver is disclosed. The method is for determining, at the receiver, a set of data symbols of a multicode signal transmitted from the transmitter. The transmitted multicode signal propagates along multiple paths as respective multipath components. These multipath components are received by the receiver as a composite signal from which the set of data symbols of the multicode signal is obtained. The method includes estimating each multipath component, path by path, based on a modified composite signal. The modified composite signal is the result of subtracting a sum of previously estimated multipath components, if any, from the composite signal. The method further includes estimating the set of data symbols of the multicode signal based on the estimated multipath components. A receiver wherein the method is implemented is also disclosed.
    • 公开了一种包括发射机和接收机的多码分多址(cdma)系统中的多路径干扰消除方法。 该方法用于在接收机处确定从发射机发送的多码信号的一组数据符号。 传输的多码信号作为相应的多径分量沿着多个路径传播。 这些多径分量由接收机作为复合信号接收,从该信号获得多码信号的数据符号组。 该方法包括基于经修改的复合信号来估计每个路径路径的每个多路径分量。 修改的复合信号是从复合信号中减去先前估计的多径分量之和(如果有的话)的结果。 该方法还包括基于估计的多路径分量估计多码信号的数据符号集合。 还公开了实现该方法的接收器。
