摘要： Teachings presented herein offer improved symbol block detection by including a decoder unit in a demodulation system. Utilizing a decoder unit in a demodulation system can significantly enhance symbol block detection because the decoder can produce bit likelihood values (soft bit values), and these bit likelihood values can be used to construct a set of candidate symbol values. Advantageously, this set of candidate symbol values is more likely to contain the actually transmitted symbol(s) than if the decoder unit was not used in the demodulation system.
摘要翻译：本文提出的教学通过在解调系统中包括解码器单元来提供改进的符号块检测。在解调系统中使用解码器单元可以显着增强符号块检测，因为解码器可以产生位似然值（软比特值），并且这些比特似然值可以用于构建一组候选符号值。有利地，与在解调系统中不使用解码器单元相比，这组候选符号值更可能包含实际发送的符号。

摘要： The present invention provides systems and methods that enable a base station to consume less power. According to an embodiment of the invention, the base station reduces its power consumption by not continuously broadcasting control information. In such an embodiment, a mobile station that seeks access to a network to which the base station provides access does not search for broadcast control information prior to transmitting an access message to the base station, but rather simply transmits on a predetermined access channel an access request message. A base station that receives the access request message may unicast control information to the mobile station.

摘要： With a nonparametric G-Rake receiver, combining weights may be determined using a nonparametric mechanism in multiple-input, multiple-output (MIMO) scenarios. In an example embodiment, a method for a receiving device having a nonparametric G-Rake receiver entails calculating an impairment covariance matrix and determining combining weights. More specifically, the impairment covariance matrix is calculated based on a pilot channel using a nonparametric mechanism in a MIMO scenario in which a code-reuse interference term exists. The combining weights are determined for the nonparametric G-Rake receiver responsive to the impairment covariance matrix and by accounting for the code-reuse interference term.

摘要： In a receive node (230) of a wireless network (100), an iterative multi-user multi-stage interference cancellation receiver (500, 1400, 1700) is used. The receiver (500, 1400, 1700) performs code-averaged equalization and chip chip-level code-specific interference over-cancellation on the received signals. This can result in a unified interference cancellation processing, and can avoid cumbersome calculations of code cross correlations that is required in symbol-level interference cancellation. A symbol-level code-averaged desired signal add-back is performed to address the over- cancellation of some desired signals.

摘要： A combination of parametric and non-parametric approaches are disclosed for enabling pilot-based SINR estimation, for MIMO systems. The pilot-based SINR estimation embodiments account for preceding applied during either single-stream or multi-stream data transmission. The pilot-based SINR estimation embodiments also account for code reuse interference which arises during multi-stream data transmission when spreading codes are reused on the data channel. Accordingly, mismatches that exist between the data channel and the pilot channel because of preceding and/or code reuse are inherently accounted for by the pilot-based SINR estimation, embodiments disclosed herein.
