    • A method and system for implementing antenna verification in a closed loop transmit diversity system. The method includes the step of processing a received signal using a finger processors to generate a plurality of finger outputs. The mobile station is communicatively coupled to a base station. The method also includes the step of combining each of the finger outputs using a combiner to produce a plurality of intermediate results. The intermediate results are obtained prior to a final summation performed by the combiner. An antenna verification process is performed using the intermediate results, the intermediate results in the pre-slot FSM (feedback signaling message) calculation from an FSM encoder, and the pre-slot FSM from the FSM encoder to efficiently estimate the error of the FSM signal and obtain the correct channel estimation by keeping the weight factors generated in a mobile station and used in a base station consistent with each other, thereby reducing the effects of FSM error between the base station and the mobile station.
    • 一种用于在闭环发射分集系统中实现天线验证的方法和系统。 该方法包括使用手指处理器处理接收信号以产生多个手指输出的步骤。 移动台通信地耦合到基站。 该方法还包括使用组合器组合每个手指输出以产生多个中间结果的步骤。 在由组合器执行的最终求和之前获得中间结果。 使用中间结果执行天线验证过程,中间结果来自FSM编码器的前置时隙FSM(反馈信令消息)计算和来自FSM编码器的前置时隙FSM以有效地估计FSM信号的误差 并通过保持在移动台中生成并在基站中使用的加权因子彼此一致来获得正确的信道估计,从​​而减少基站与移动台之间的FSM误差的影响。

    • Method and apparatus for dynamically allocating IP addresses in a wireless IP network. IP address servers determine the requisite IP address pools and guard bands for individual network cells to guarantee fair access to the network and facilitate handoff host handoff from a prior cell to a new cell. IP address servers also prioritize handoff and resident hosts that request an IP address from the IP address server. In particular, IP address servers assign a higher priority to handoff hosts over resident hosts that request an IP address from an IP address server in order to maintain a preestablished handoff host network connection instead of dropping a handoff host connection in favor of a new resident host network connection. Finally, each cell is allocated a minimum number of IP addresses to ensure a certain level of fair access to the network regardless of the cell wherein a handoff or resident host resides.
    • 在无线IP网络中动态分配IP地址的方法和装置。 IP地址服务器确定各个网络小区所需的IP地址池和保护频段,以保证对网络的公平访问,并促进从先前小区到新小区的切换主机切换。 IP地址服务器还优先处理从IP地址服务器请求IP地址的切换和驻留主机。 特别地,IP地址服务器分配更高的优先级,以便通过从IP地址服务器请求IP地址的常驻主机切换主机,以便维护预先建立的切换主机网络连接,而不是丢弃切换主机连接以利于新的驻留主机 网络连接。 最后,每个小区被分配最小数量的IP地址,以确保一定程度的公平接入网络,而不管切换或驻留主机所在的小区。
