Abstract
A PN code hopping method for mitigating cross-correlation interference is provided. The method includes the steps of providing a memory device and storing a plurality of PN codes, where each PN code is associated with a useful life cycle. The PN codes are pseudo-randomly accessed and used to spread a modulated signal for their respective useful life cycle before another PN code is pseudo-randomly retrieved.
