摘要： A code division multiple access communication system transmits a pilot and traffic signal over a shared spectrum. The pilot and traffic signal have an associated code and are received over the shared spectrum. The received signals are sampled and the samples are delayed to produce a window. A weighted value for each despread pilot code window sample is determined using an adaptive algorithm. Each window sample is despread with a traffic code. Each despread traffic code window sample is weighted according to a weight corresponding to its respective pilot code sample.

摘要： A transmitter transmits a spread spectrum pilot and data signal. Each signal has an associated chip code. A receiver receives the transmitted pilot and data signal. The received pilot signal is filtered using the pilot chip code and weights are determined for components of the received pilot signal using an adaptive algorithm. The received data signal is weighted by the determined weights and filtered with the data signal chip code to recover data from the received data signal.

摘要： A method for determining the validity of a most significant path in a wireless communication system wherein data is transmitted in frame units in a multipath environment begins by accumulating a correlated data sequence N times, each time at a frame offset apart from the previous time. A preliminary noise estimate (PNE) is calculated as an average of the accumulated data values. A preliminary noise threshold (PNT) is calculated according to the equation C1×PNE. A final noise estimate (FNE) is calculated as the average of accumulated data values below the PNT. A final noise threshold (FNT) is calculated according to the equation C2×FNE. The validity of the most significant path is determined if the most significant path value is greater than the FNT.
摘要翻译：用于确定无线通信系统中最重要路径的有效性的方法，其中以多路径环境中的帧为单位传输数据的开始是通过累积相关数据序列N次，每次与之前的时间相隔一帧偏移。初步噪声估计（PNE）被计算为累积数据值的平均值。根据等式C1×PNE计算初步噪声阈值（PNT）。最终噪声估计（FNE）被计算为低于PNT的累积数据值的平均值。根据等式C2×FNE计算最终噪声阈值（FNT）。如果最显着的路径值大于FNT，则确定最重要路径的有效性。

摘要： A method and apparatus for handling a control channel for carrier aggregation in wireless communications. The method includes determining which component carrier to listen to, detecting the downlink control channel, processing mapping information related to downlink and uplink transmissions and operating discontinuous reception with respect to carrier aggregation. The method also includes detecting a component carrier, determining the component carrier type and locating the anchor component carrier, if necessary, where the anchor component carrier carries the carrier aggregation information.
