Abstract
A low-cost and power-efficient communication system using digital frequency centering techniques suitable for millimeter-wave wide-bandwidth bands with mostly digital components. Significant circuitry in the frequency source can be switched-off, thus conserving power. With the use of non-coherent detection, power consumption can be further reduced as higher phase noise and lower frequency accuracy can be tolerated. In the first embodiment frequency centering is achieved with a multiple-state system which compares a frequency dependent unique state to a programmed or hardwired desired state. In an alternative embodiment this multiple-state system is implemented by means of a microcontroller through either software or hardware.
