摘要：
Methods and apparatus for wireless communications are described. A method of wireless communications includes determining an energy for a first signal received at a first finger of a rake receiver after a reference signal is received at a second finger of the rake receiver, determining an energy for a second signal received at a third finger of a rake receiver before the reference signal is received at the second finger of the rake receiver, and selecting the first signal as a new reference signal when the energy of the first signal exceeds the energy of the second signal by a predefined threshold amount. In another aspect, a method includes assigning a signal received at a rake receiver to a finger of the rake receiver, and deassigning the finger if the signal has an energy level below a preselected lock threshold energy for a predefined time.
摘要（中）：
描述用于无线通信的方法和装置。 一种无线通信方法包括：在rake接收机的第二个手指接收到参考信号之后，确定在rake接收机的第一个手指处接收的第一个信号的能量，确定在第三个手指处接收到的第二个信号的能量 在前置雷达接收机的第二个手指接收参考信号之前的前置接收机，并且当第一信号的能量超过第二信号的能量预定的阈值量时，选择第一信号作为新的参考信号。 在另一方面，一种方法包括将在瑞克接收机处接收的信号分配给瑞克接收机的手指，以及如果信号在预定义时间内具有低于预先选择的锁定阈值能量的能级，则解除指配。
