    Abstract: A wireless transmitter comprises an input configured to receive a data signal. A mixer mixes the data signal with a correction signal producing a corrected signal. The correction signal changes a phase in the data signal to compensate for a measured phase error at a desired receiver. A modulator modulates the corrected signal to radio frequency as a radio frequency signal. An antenna radiates the radio frequency signal.

    Abstract: The present invention is an apparatus for reducing transmission errors by a user equipment (UE) when transmitting a communication signal. An RF communication signal is received at the UE and analyzed for errors. A correction signal is then generated based upon the analysis. Prior to transmission of the communication signal from the UE, the communication signal is corrected using the correction signal.

    Abstract: A subscriber cluster unit for a wireless telecommunication system provides a wireless interface with a base station for a plurality of subscriber units. The cluster unit has a plurality of frequency agile modems for processing wireless communications with the base station and a plurality of subscriber line circuits, each for providing a telecommunication connection with a subscriber unit. A control processor assigns a modem for each communication between the base station and a selected subscriber unit which is coupled to one of the line circuits and associates that line circuit with the assigned modem for that communication. Thus, a subscriber unit coupled with any of the line circuits can communicate with the base station via any of the modems.

    Abstract translation: 用于无线电信系统的用户群集单元为多个用户单元提供与基站的无线接口。 集群单元具有用于处理与基站的无线通信的多个频率敏捷调制解调器以及用于提供与用户单元的电信连接的多个用户线路电路。 控制处理器为基站和选择的用户单元之间的每个通信分配调制解调器，所选择的用户单元耦合到线路电路中的一个，并将该线路电路与用于该通信的所分配的调制解调器相关联。 因此，与任何线路电路耦合的用户单元可以经由任何调制解调器与基站进行通信。
