    • The present invention provides an effective way to create a virtual MIMO transmission system using mobile terminals that have only one transmit path and antenna. This is accomplished by assigning mobile terminals to a group and assigning certain shared resources and user-specific resources to those mobile terminals in the group. In a synchronized fashion, the mobile terminals will provide uplink transmission in concert, as if they were a single entity having multiple transmission paths and antennas. Preferably, the shared resources bear on how the data is transmitted, and the user-specific resources relate to pilot signals. The data transmitted may be encoded in any number of ways, and in one embodiment, the mobile terminals may relay their information to each other, such that uplink transmissions can incorporate STTD decoding or other space-time codes. The invention is applicable to virtually any multiple access technology, including OFDM, TDMA, and CDMA, preferably synchronous CDMA.
    • 本发明提供了使用仅具有一个发送路径和天线的移动终端来创建虚拟MIMO传输系统的有效方式。 这通过将移动终端分配给组并且向组中的那些移动终端分配特定共享资源和用户特定资源来实现。 以同步方式,移动终端将一起提供上行链路传输,好像它们是具有多个传输路径和天线的单个实体。 优选地,共享资源对数据的传输方式如何,并且用户特定的资源与导频信号有关。 传输的数据可以以任何数量的方式进行编码,并且在一个实施例中,移动终端可以将它们的信息彼此中继,使得上行链路传输可以包含STTD解码或其他时空码。 本发明可应用于几乎任何多址接入技术,包括OFDM,TDMA和CDMA,优选地是同步CDMA。

    • The present invention relates to decoding space time coded (STC) signals transmitted from a number of transmit antennas. First, a separate detection technique is used to determine initial decoding solutions corresponding to the symbols transmitted from each of a number of transmit antennas at a given time. For each initial solution, a limited area about the initial solution is defined. Each of the limited areas will correspond to regions including constellation points proximate the initial solution. The initial solutions are used to define a limited, multi-dimensional space. Accordingly, the initial solutions are used to reduce the search complexity associated with joint decoding by defining aAimited space about the initial solutions. Finally, a joint decoding technique is implemented within the limited space to find a final solution.
    • 本发明涉及解码从多个发射天线发射的空时编码(STC)信号。 首先,使用单独的检测技术来确定在给定时间从与多个发射天线中的每一个发送的符号相对应的初始解码解。 对于每个初始解决方案,定义关于初始解决方案的有限区域。 每个有限区域将对应于包括邻近初始解决方案的星座点的区域。 初始解决方案用于定义有限的多维空间。 因此,初始解决方案用于通过定义关于初始解决方案的限制空间来减少与联合解码相关联的搜索复杂度。 最后,在有限的空间内实现联合解码技术,找到最终解决方案。
