摘要： The present invention discloses a method for detecting orthogonal code CDMA signal implemented mainly through the following steps: estimating the total power of interference to the multi-path signals; performing matched filtering on the multi-path signals and performing maximum ratio combining on the multi-path signals by utilizing the total power of interference to the multi-path signals, to obtain the optimized matched filtering result; and performing joint detection on the optimized matched filtering result. There are two schemes for implementing: if the optimized matched filtering detection scheme is used, only the first two main steps are executed; if the joint detection scheme is used, all of the three steps are executed. In either of above two schemes, the interference code channels involved in the estimation of total power of interference to the multi-path signals are need to be selected, i.e., all of the code channels in the serving cell or the code channels in the serving cell which are not performed joint detection on are selected. As the present invention takes full advantage of the characteristic of orthogonal code as well as the channel estimation result, system performance can be improved at a lower price. The present invention is especially suitable for terminal devices in an orthogonal code Code Division Multiple Access system.
摘要翻译：本发明公开了一种用于检测正交码CDMA信号的方法，主要通过以下步骤实现：估计对多径信号的干扰总功率; 对多路径信号执行匹配滤波，并通过利用多路径信号的总干扰功率对多径信号进行最大比组合，以获得优化的匹配滤波结果; 对优化的匹配滤波结果进行联合检测。有两种实现方案：如果使用优化的匹配过滤检测方案，只执行前两个主要步骤; 如果使用联合检测方案，则执行所有三个步骤。在上述两种方案中的任一方面中，需要选择涉及对多路径信号的总干扰功率估计所涉及的干扰码信道，即服务小区中的所有码信道或服务中的码信道选择不执行关联检测的单元。由于本发明充分利用正交码的特征以及信道估计结果，可以以更低的价格提高系统性能。本发明特别适用于正交码分多址系统中的终端设备。
