<p>A mobile wireless communication device for extracting time from a spread spectrum signal including a repeating short chip code and a repeating long chip code, a ratio of the long and short chip is a non-integer having a remainder bit that accumulates over successive intervals of the chip codes. The device includes a receiver for receiving (710) the spread spectrum signal, means for determining corresponding bit numbers (720) of the long and short chip codes at a particular time, means for determining a number of accumulated remainder bits (730) as a function of the bit numbers of the long and short chip codes, and means for determining time (740) as a function of the number of accumulated remainder bits.</p> |
