Abstract

ABSTRACT

A receiver receives a transmitted digital signal having a synchronization signal and information signals.
The receiver synchronizes to the synchronization signal and detects predetermined signals within the information signals. When it is determined that an information signal is substantially different from the predetermined signals, power is conserved for the remainder of the information signal.
