    • A joint detection reception apparatus and method, which are utilized irrespective of a length of an orthogonal code in a TD-CDMA communication system. The joint detection reception method for creating a system matrix associated with a joint detection receiver in the same time slot includes the steps of a) repeating and partitioning individual channelization codes having variable lengths, and creating channelization code blocks having the same lengths, b) performing a convolution operation between the repeated and partitioned channelization code blocks and a channel impulse response, and acquiring combined impulse responses, c) grouping the combined impulse responses to construct sub-block matrices for a joint detection system, d) arranging the sub-block matrices for the joint detection system to be shifted by a predetermined column distance, and constructing a joint detection system matrix, and e) extending the joint detection system matrix to a squared-format matrix to create a block-circulant squared matrix.
    • 无论TD-CDMA通信系统中的正交码的长度如何,都使用联合检测接收装置和方法。 用于在相同时隙中创建与联合检测接收机相关联的系统矩阵的联合检测接收方法包括以下步骤:a)重复和分割具有可变长度的各个信道化码,并创建具有相同长度的信道化码块,b)执行 重复和分割的信道化码块之间的卷积运算和信道脉冲响应,以及获取组合脉冲响应,c)将组合的脉冲响应分组以构建用于联合检测系统的子块矩阵; d)将子块矩阵 用于使联合检测系统偏移预定列距离,以及构建联合检测系统矩阵,以及e)将联合检测系统矩阵扩展为平方格式矩阵以创建块循环平方矩阵。
