Abstract
Unique methods and apparatus for maintaining timing in spread spectrum communications are described. One method involves the steps of repeatedly incrementing an N-bit master binary counter at a chip rate to provide a count that rolls over at or near the end of a nominal zero-offset pseudorandom noise (PN) sequence having a length of 2 . The method includes the further steps of, for each counter of a plurality of N-bit slave binary counters, repeatedly incrementing an N-bit slave binary counter at the chip rate to generate a count that is out-of-phase with the count associated with the N-bit master binary counter by a base station offset value and a path delay value.
