    • PROBLEM TO BE SOLVED: To provide multiplexing for a multicarrier cellular communication system. SOLUTION: For quasi-orthogonal multiplexing in an OFDMA system, multiplex traffic channels are defined for each base station. The traffic channels in each set are orthogonal to one another and can be pseudo-random, with respect to the traffic channels in each of the other sets. The minimum number of sets of channels is used to support a given number of terminals selected for data transmission. Each terminal transmits the data and pilot symbols on its traffic channel. A base station receives data transmissions from all terminals and can perform receiver spatial processing on received symbols with spatial filter matrices to obtain detected data symbols. The spatial filter matrix for each subband can be derived, based on channel response estimates for all terminals transmitting on that subband. COPYRIGHT: (C)2011,JPO&INPIT
    • 要解决的问题:提供多载波蜂窝通信系统的复用。 解决方案:对于OFDMA系统中的准正交复用,为每个基站定义复用业务信道。 每组中的业务信道彼此正交,并且相对于其他集合中的每一个的业务信道可以是伪随机的。 通道的最小数量用于支持选定数据传输的给定数量的终端。 每个终端在其业务信道上发送数据和导频符号。 基站从所有终端接收数据传输,并且可以利用空间滤波器矩阵对接收符号执行接收机空间处理,以获得检测到的数据符号。 可以基于在该子带上传输的所有终端的信道响应估计来导出每个子带的空间滤波器矩阵。 版权所有(C)2011,JPO&INPIT
