摘要： In a multicarrier modulation communications system, a change of a bit allocation table for the multiple subchannels or tones is notified from a transmitter to a receiver by a change in the inversion state of synchronization symbols provided in superframes of transmitted multicarrier symbols, successive changes of the bit allocation table being indicated by opposite changes of the inversion state of the synchronization symbols, respectively from non-inverted to inverted synchronization symbols and from inverted to non-inverted synchronization symbols. This provides resistance to errors and facilitates rapid recovery in the event that errors occur. A superframe number can also be used to identify when the inversion state of the synchronization symbols is to be changed.

摘要： The present invention provides methods and systems for a flyback converter arranged with synchronous rectifier MOSFETS in such a manner that they operate with a common source potential while still providing for the use of a stacked output winding. With a common source potential, a single rectifier control voltage can be used to operate the rectifiers for multiple outputs greatly simplifying the control circuit. Advantageously, the present invention maintains the inherent simplicity of the flyback design while enabling designs with well-regulated multiple voltage outputs and the efficiency benefits of synchronous rectification.
