  • Data dithering apparatus and method
    Patent number: 7200184
    Abstract: A waveform having an amplitude that varies to thereby represent corresponding data values is dithered to further shape the waveform so that use of the dithered waveform to create a corresponding FSK signal will result in a signal having a smoothed frequency domain profile. In various embodiments, the waveform amplitude is varied with respect to periodicity of variation, extent of variation, and duration of variation.

  • Method and apparatus for synchronizing transmissions
    Publication number: 20050259773
    Abstract: In order to properly synchronize a communication system (100), a synchronization pulse is combined with DC power distribution. This is accomplished by interrupting the DC power that is supplied to each access point radio (102). The interruption occurs on a rising edge of the precision timing reference and lasts for a predetermined time. This pulsed-DC signal is utilized to prevent transmission by an access point during a receive cycle of other access points.
