Abstract
The present invention relates to a slot clock generator for high data rate pulse position modulation (PPM), including: a set of clocks with predetermined frequencies that are mutually prime in pairs, the set of clocks which synthesizes and accumulates changes in clock states at a rate corresponding to a slot rate that is greater than a slot rate of any single clock in the set.
Claims5
A slot clock generator for high data rate pulse position modulation (PPM), comprising:
- a set of clocks with predetermined frequencies that are mutually prime in pairs, said set of clocks which synthesizes and accumulates changes in clock states at a rate corresponding to a slot rate for a synthetic slot clock that is greater than a slot rate of any single clock in said set, wherein a lookup table is used to synthesize said slot rate of said clock states by solving a set of simultaneous modular equations on said clock states by producing a composite modulus that is larger than a cardinality of a PPM signal.
(canceled)
The slot clock generator of claim, 1 wherein said PPM signal is a composite signal including two or more modulation dimensions.
