Method and apparatus for the generation of frequency hopping sequences

摘要

A frequency hopping generator comprises an XOR processing module and a PERM (permutation) processing module arranged in series. The XOR and PERM modules act directly on input clock lines as a function of a selection address. The hopping number sequence generated by the frequency hopping generator can be changed in real-time by changing the selection addresses, while the phase of the sequence can be changed in real-time by changing the clock value on the clock lines. The frequency generator finds exemplary use in rapidly switching between different piconets in a wireless scatter network.
