摘要： A selective decision-feedback detector for the space-time block code which provides both diversity and spatial multiplexing. To detect a received code block of transmitted symbols, the channel matrix is properly preprocessed with the real and imaginary parts decoupled, and the selective decision-feedback detector makes multiple decisions on the same block upon differently permuted channel matrix and generates multiple candidates for the results. The indicators of the decision errors associated with the candidates are compared, and one of the candidates with the minimum error is selected by a selector as the decided symbols to be used for further processing at a receiving station.

摘要： The present disclosure relates generally to systems and methods for timing synchronization. Uplink synchronization is a necessary component of a UE operating in a mobile, wireless network. Reliable uplink synchronization generally requires regular uplink transmission containing reference signals. A method is provided that defines a burst period for sending the reference signals, determines an interval between the reference signals, and sends a timing instruction message that includes the burst period and the determined interval. A second method is provided that receives the timing instruction message and sends the reference signals in accordance with the timing instruction.

摘要： The application relates to a method for communication from a second mobile station to a base station or vice versa. In a given multiframe, a first SACCH slot associated with the second mobile station is communicated (i.e. received or transmitted or both) via the second VAMOS subchannel. In the same multiframe, a redundant second SACCH slot associated with the second mobile station is communicated. The communicating step is performed either by the second mobile station or by the base station. The second SACCH slot may be communicated via the second VAMOS subchannel, in case the second VAMOS subchannel is in DTX mode. In an alternative embodiment, the second SACCH slot may be communicated via a first VAMOS subchannel, in case the first VAMOS subchannel is in DTX mode, wherein the first and second VAMOS subchannels share a common time slot and have the same carrier frequency. Both embodiments may be combined: I.e. in case the second VAMOS subchannel is in DTX mode, the second SACCH slot is communicated via the second VAMOS subchannel, and in case the first VAMOS subchannel is in DTX mode, the second SACCH slot may be communicated via the first VAMOS subchannel.
摘要翻译：本申请涉及从第二移动站到基站的通信的方法，反之亦然。在给定的多帧中，经由第二VAMOS子信道传送与第二移动站相关联的第一SACCH时隙（即，接收或发送或两者）。在相同的多帧中，传送与第二移动站相关联的冗余的第二SACCH时隙。通信步骤由第二移动站或基站执行。在第二VAMOS子信道处于DTX模式的情况下，可以经由第二VAMOS子信道来传送第二SACCH时隙。在替代实施例中，在第一VAMOS子信道处于DTX模式的情况下，可以经由第一VAMOS子信道来传送第二SACCH时隙，其中第一和第二VAMOS子信道共享公共时隙并具有相同的载波频率。两个实施方案可以组合：即在第二VAMOS子信道处于DTX模式的情况下，经由第二VAMOS子信道传送第二SACCH时隙，并且在第一VAMOS子信道处于DTX模式的情况下，可以经由第一VAMOS子信道来传送第二SACCH时隙。

摘要： The present disclosure provides for a method and apparatus for efficient cross-correlation between a reference sequence and a received sequence in a wireless communication system. The reference sequence includes a concatenation of sign-adjusted sub-sequences, the sign adjustments determined by a first sign sequence of a set of sign sequences. For example, the reference sequence may be an alternating concatenation of sign-adjusted Golay complementary pair sub-sequences. The received sequence is shifted to provide a plurality of time shifted sequences that are then cross-correlated with the sub-sequences to form a set of partial cross-correlations. The partial cross-correlations are sign-adjusted using the first sign sequence and combined to produce the cross-correlation between the reference sequence and the received sequence. The cross-correlations so produced may be used for channel signature (e.g. PHY-type) identification and/or channel impulse response estimation.
摘要翻译：本公开提供了一种用于无线通信系统中的参考序列和接收序列之间的有效互相关的方法和装置。参考序列包括符号调整的子序列的级联，符号调整由一组符号序列的第一符号序列确定。例如，参考序列可以是符号调整的Golay互补对子序列的交替连接。接收到的序列被移位以提供多个时移序列，然后与子序列交叉相关以形成一组部分交叉相关。部分互相关使用第一符号序列进行符号调整，并被组合以产生参考序列与接收到的序列之间的互相关。如此产生的互相关可用于信道签名（例如，PHY类型）识别和/或信道脉冲响应估计。
