1. A method of receiving a spread spectrum signal at a mobile terminal, including the steps of:
- processing the spread spectrum signal for the purposes of signal acquisition and signal tracking,monitoring a movement of the mobile terminal;
deriving a signal indicative of a characteristic of the movement of the mobile terminal; and
changing a mode of processing of the spread spectrum signal by narrowing a ranging of frequencies swept during signal acquisition in response to the signal indicative of the characteristic of the movement of the mobile terminal.
